The 90-Day Vascular Reset

A cardiologist’s evidence-based protocol for the first year of not dying early

I want to give you a protocol. Not a wellness program. Not a lifestyle overhaul. A protocol — the way cardiologists think about clinical interventions: sequential, specific, evidence-graded, with clear endpoints and clear re-assessment timelines. The protocol I am about to give you has no supplements to buy, no app to download, and nothing you need to do in the first week except make a phone call. Every element is calibrated to the evidence base we have reviewed in this book. Every timeline is based on how the biology actually changes. The protocol is not designed to make you live forever. It is designed to give your cardiovascular system a fundamentally different set of inputs than it has been receiving — and to measure whether those inputs are producing the changes the evidence says they should.

This is the 90-Day Vascular Reset. It begins with a conversation with your doctor.

Before we get to the four pillars, I want to say something about sequencing. Every man I have watched fail at health change did it the same way: he tried to do everything at once. He downloaded five apps, hired a nutritionist, cut carbohydrates, started waking at 5 a.m., and was done by week three. The biology of behavior change does not work that way. The prefrontal cortex — the executive function center responsible for planning and impulse control — is finite in its daily energy allocation. You already use most of it running your life. Asking it to simultaneously manage a new diet, a new exercise regimen, new sleep hygiene, and a new physician relationship is not ambition. It is architectural failure. The protocol I’m giving you is sequential by design, because sequential is what works. You do not move to the next layer until the previous layer is set.

The Protocol Philosophy: Evidence-Graded, Sequential, Sustainable

The hierarchy of interventions. Not everything in this protocol carries the same evidence weight. I want to be explicit about that, because the wellness industry is not. Every protocol element below carries a Honesty Scale rating (1–5) based on the SDE framework: 5 = multiple RCTs or systematic reviews; 4 = multiple cohort studies, consistent direction; 3 = single good RCT or small studies; 2 = mechanistically plausible, limited trials; 1 = not supported. You will see these ratings throughout. They are not excuses to skip the 3s and 2s — they are invitations to be honest with yourself about what you are doing and why.

Why we start with measurement. The entire protocol presupposes one thing: that you know your numbers. Not approximately. Not from a physical three years ago. This week’s numbers. Before you change a single behavior, before you take a single medication, before you rearrange your morning, you need to know what you are working with. A man who starts exercising without knowing his CAC score may be exactly the man whose first exertional activity ruptures a vulnerable plaque. A man who starts restricting calories without knowing his fasting insulin may be optimizing the wrong dial. Measurement is not a bureaucratic step. It is the clinical foundation on which everything else stands.

The Four Pillars of the Reset

PILLAR ONE: MOVE

Protocol Element 1 — Resistance Training (2–3× per week) Honesty Scale: 5 / Solid

The evidence for resistance training in cardiovascular risk reduction has matured substantially in the last decade, and it deserves more clinical respect than it receives in standard cardiology practice. A 2022 meta-analysis published in the British Journal of Sports Medicine (Momma et al., 74,000 participants across 16 prospective cohort studies) found that muscle-strengthening activities were independently associated with a 17% lower risk of all-cause mortality, a 14% lower risk of cardiovascular disease, and a 12% lower risk of type 2 diabetes — with greatest risk reduction at 30–60 minutes per week. That last number is worth sitting with. Thirty minutes per week. That is less than one episode of television.

The mechanisms are multiple. Resistance training improves insulin sensitivity through GLUT4 transporter upregulation in skeletal muscle — the same pathway that metformin activates pharmacologically. It modestly but consistently reduces systolic blood pressure (mean −4 to −6 mmHg in meta-analysis data). It maintains or increases testosterone in older men through pituitary-gonadal axis stimulation. And it preserves lean muscle mass, which functions as the body’s primary glucose disposal organ and whose decline is one of the most reliable predictors of metabolic deterioration after 40.

What to do: Two sessions per week of compound resistance movement — squat pattern, hip hinge, push, pull. Not five days of isolation exercises. Not a CrossFit class three days before your first rest day. Two sessions of 45–60 minutes, with progressive overload over 12 weeks. If you haven’t lifted in five years, start with machines, not free weights. The injury is not the protocol.

Protocol Element 2 — Zone 2 Cardio (3× per week, 30–45 minutes) Honesty Scale: 4 / Promising

Zone 2 training — sustained aerobic effort at 60–70% of maximum heart rate, where you can hold a conversation with mild effort — is the metabolic foundation of cardiovascular preservation. At this intensity, you are primarily oxidizing fat, maximally stimulating mitochondrial biogenesis, and training the aerobic substrate that declines most reliably in men between 40 and 55. Joyner and Coyle’s landmark 2008 review in the Journal of Physiology established VO2max — the ceiling of your aerobic capacity — as the single strongest predictor of all-cause and cardiovascular mortality across population studies, with each MET increase in cardiorespiratory fitness associated with approximately 15% reduction in cardiovascular mortality. Zone 2 is how you build that ceiling.

The practical frame: 30–45 minutes of brisk walking, cycling, or swimming at a pace where you are breathing harder than normal but could sustain a conversation. Three days per week. No app required. No wearable required. A rough but reliable proxy: you should be able to talk in sentences, but not want to.

Protocol Element 3 — IMST (5 minutes per day, 6 days per week) Honesty Scale: 3 / Early

Inspiratory Muscle Strength Training deserves a place in this protocol not because the evidence is overwhelming — it is a single well-designed RCT — but because the finding is remarkable enough that omitting it would be a disservice to any man with borderline hypertension. Craighead et al.’s 2021 randomized controlled trial published in the Journal of the American Heart Association enrolled 36 men and women with above-normal systolic blood pressure (mean age 55) and assigned them to six weeks of high-resistance inspiratory muscle training — 30 breaths per day at 75% of maximal inspiratory pressure, using a handheld device costing roughly $30–$50. The result was a mean systolic blood pressure reduction of 9 mmHg. To put that in clinical context: that reduction exceeds what most first-line antihypertensive medications achieve in clinical trials, and it was achieved in five minutes per day. The same group reported improvements in flow-mediated dilation — the gold-standard measure of endothelial function — of 45%.

I recommend IMST to men with systolic blood pressure above 130 mmHg who have not yet responded fully to lifestyle modification, and to any man who travels frequently and cannot maintain consistent exercise. A 5-minute protocol that requires nothing but a device and a chair is the most accessible cardiovascular intervention that almost no physician is recommending yet.

PILLAR TWO: EAT

Protocol Element 4 — The Anti-Inflammatory Default Honesty Scale: 4 / Promising

I am not going to give you a diet. The dieting literature is sufficiently contested, sufficiently compromised by industry funding, and sufficiently resistant to long-term adherence that prescribing a named diet in this protocol would be clinically irresponsible. What I am going to give you is a framework derived from the three most consistent findings in cardiovascular nutrition research.

Reduce ultra-processed food. The evidence here is as close to a 5 as nutrition science gets. Monteiro et al.’s NOVA framework, validated in multiple prospective cohort studies, classifies food by degree of industrial processing, not nutrient composition. Men in the highest quartile of ultra-processed food consumption show 26% higher risk of incident coronary heart disease versus the lowest quartile, controlling for total caloric intake, macronutrient composition, and known confounders. Ultra-processed food — food manufactured with industrial ingredients not used in home cooking, designed for palatability rather than satiety — drives insulin dysregulation through multiple mechanisms independent of its macronutrient content. You do not need to know the mechanism to act on the finding. If it has more than five ingredients and was manufactured in a plant, eat it less often.

Protect your omega-3 status. I discussed the Omega-3 Index in an earlier chapter. The relevant protocol point here is behavioral: most American men have an Omega-3 Index of 4–5%, against a cardioprotective target of 8–12%. The REDUCE-IT trial (Bhatt et al., NEJM 2019, N=8,179) demonstrated that high-dose icosapentaenoic acid (EPA) at 4g/day in men with elevated triglycerides and established cardiovascular disease reduced major adverse cardiovascular events by 25%. That is a pharmaceutical-grade trial. You can test your baseline Omega-3 Index for approximately $50. If you’re going to take fish oil, know whether it’s working.

Anchor your last meal earlier. The chrononutrition literature — the science of when we eat, not just what we eat — is emerging rapidly. What is established with reasonable consistency is that eating within two to three hours of sleep elevates nocturnal blood glucose, disrupts sleep architecture, and blunts the overnight fasting window that drives the morning cortisol reset. Moving your last meal to 7 p.m. or earlier — not for caloric restriction but for circadian alignment — is an intervention with almost no cost and reasonable mechanistic support. (Honesty Scale: 2 / Mechanistic — the evidence in healthy adults is observational, not RCT.)

Protocol Element 5 — The GLP-1 Conversation Honesty Scale: 5 / Solid

If you are carrying more than 25 pounds above your optimal weight and have a documented cardiovascular risk factor — hypertension, dyslipidemia, prediabetes, or a CAC score above zero — you and your physician need to discuss GLP-1 receptor agonists. This is not optional, and it is not a conversation about vanity. The SELECT trial (NEJM November 2023, N=17,604 adults with obesity or overweight and established cardiovascular disease, no diabetes) was the first weight-management trial in history to demonstrate primary cardiovascular mortality benefit: once-weekly semaglutide reduced major adverse cardiovascular events by 20%, nonfatal myocardial infarction by 28%, and cardiovascular death in the primary analysis. The FDA subsequently approved semaglutide for cardiovascular risk reduction independent of its weight-loss indication.

This is the most significant cardiovascular pharmacology development of 2023–2024, and most men outside the cardiology world do not know about it. If your physician has not raised it, you should. The conversation is: “My BMI is above 30 and I have a cardiovascular risk factor. Given the SELECT trial findings, should we discuss semaglutide?”

Protocol Element 5b — The Statin Conversation Honesty Scale: 5 / Solid

I want to address the statin question directly, because it is the conversation that happens most often in the space between Chapter 12’s lab results and the clinical decision about medication. A man who has read this far may have concluded — correctly — that his ApoB is too high, his CAC score is above zero, and his hs-CRP is elevated. He may have also concluded — from any number of wellness publications — that statins are dangerous, overprescribed, or a pharmaceutical industry conspiracy. I want to address both things.

The evidence for statin therapy in reducing cardiovascular events is among the strongest in clinical pharmacology. The 2021 Cochrane review of statin therapy in primary prevention — pooling data from 27 RCTs covering over 174,000 participants — confirmed a 25% relative risk reduction in major cardiovascular events, 30% reduction in stroke, and 14% reduction in all-cause mortality, with no significant increase in serious adverse events including cancer or rhabdomyolysis. Muscle symptoms occur in approximately 5–10% of patients but are reversible on dose reduction or medication change. The cognitive concerns raised in some observational studies have not been replicated in controlled trials. The evidence is strong. The decision, however, is not automatic.

The statin decision framework I use in my clinic is this: ApoB above 90 mg/dL in a man with any risk factor (CAC >0, hypertension, prediabetes, smoking history, family history of premature CVD) is a conversation starter, not an automatic prescription. The absolute risk reduction matters — a man with a 5% 10-year ASCVD risk who takes a statin reduces his event probability by approximately 1.25 percentage points. A man with a 20% 10-year risk reduces his probability by approximately 5 percentage points. The same drug, the same relative risk reduction, dramatically different absolute benefit. This is the calculation your physician should be doing with you, using your numbers, at your appointment. If that conversation is not happening, you are not receiving complete care.

If you are already on a statin, the most important question is whether your ApoB target has been reached — not whether your LDL has normalized. The European Society of Cardiology guidelines set ApoB targets of <65 mg/dL for very-high-risk patients and <80 mg/dL for high-risk patients. Many men on statins have LDL values in the acceptable range but ApoB values still above target because their triglycerides remain elevated and their lipoprotein particle number has not been optimized. The target is the particle, not the cholesterol mass.

PILLAR THREE: SLEEP

Protocol Element 6 — Sleep Architecture Audit Honesty Scale: 5 / Solid

Sleep is not a soft intervention. The data on sleep and cardiovascular mortality is as strong as the data on blood pressure and cholesterol. Javaheri et al.’s 2024 state-of-the-art review in the Journal of the American College of Cardiology provides the most current mechanistic synthesis: untreated obstructive sleep apnea — present in an estimated 20–30% of men in this age cohort, with 80% undiagnosed — drives intermittent hypoxia, chronic sympathetic activation, nocturnal blood pressure surge, endothelial dysfunction, and atrial fibrillation. These are not theoretical downstream consequences. They are measured, dose-dependent, and partially reversible with CPAP treatment.

The first protocol step is a four-question screen. The STOP-BANG questionnaire — Snoring, Tired, Observed apneas, high blood Pressure, BMI above 35, Age over 50, Neck circumference above 40 cm, Gender male — takes 90 seconds. If you score 3 or above, you are at intermediate-to-high risk for OSA and a formal sleep study is indicated. Not a sleep app. Not a wearable. A polysomnography or home sleep test ordered by a physician. This is the cardiovascular screening most men in this age cohort are missing, and it is the one most likely to explain the fatigue, the blood pressure that doesn’t respond fully to medication, the fragmented nights, and the low testosterone that has been attributed to stress.

What to do: Complete the STOP-BANG screen today. If you score ≥3, ask your physician for a referral to a sleep medicine specialist or directly for a home sleep test. This is a conversation that takes one sentence.

Protocol Element 7 — Sleep Hygiene (Evidence-Graded) Honesty Scale: 4 / Promising

Once OSA has been ruled out or is under treatment, the behavioral architecture of sleep matters. The evidence-graded list, in order of effect size:

1. Consistent wake time (7 days per week, regardless of bedtime) — the strongest behavioral anchor for circadian rhythm; maintains adenosine pressure. (Honesty Scale: 4)
2. Temperature — sleeping at 65–68°F consistently facilitates the core temperature drop that initiates slow-wave sleep. (Honesty Scale: 3)
3. Light exposure — morning bright light (10–15 minutes outdoors or via a 10,000-lux lamp) advances the circadian phase in evening chronotypes. Screen light after 10 p.m. is a minor factor compared to morning light, which is the stronger lever. (Honesty Scale: 4)
4. Alcohol — even moderate alcohol (1–2 drinks) within three hours of sleep consistently suppresses REM and slow-wave sleep architecture. It may facilitate sleep onset while simultaneously destroying sleep quality. If you drink in the evenings and wonder why you feel tired despite 7–8 hours in bed, this is why. (Honesty Scale: 5)

Protocol Element 8 — Sauna (3–4× per week, 20 minutes) Honesty Scale: 4 / Promising

The Finnish data on sauna use is among the most consistent findings in cardiovascular epidemiology outside of pharmacological trials. Laukkanen, Kunutsor, and colleagues’ analyses of the Kuopio Ischaemic Heart Disease Risk Factor study (N=2,315 Finnish men, 20-year follow-up, published in JAMA Internal Medicine 2015) found a dose-dependent relationship between sauna frequency and cardiovascular outcomes: men using sauna 4–7 times per week had 40% lower cardiac mortality, 46% lower risk of sudden cardiac death, and 66% lower risk of dementia compared to once-per-week users. Mechanistically, sauna mimics moderate-intensity exercise hemodynamically — heart rate rises to 120–150 bpm, cardiac output doubles — and consistent sauna exposure improves arterial compliance, reduces blood pressure, and modestly improves HRV.

The limitation is important to state: this is a Finnish cohort study, not an RCT. Sauna users in that culture are more socially integrated, more physically active, and enjoy higher socioeconomic status than non-users — all independent cardiovascular protective factors. The association is real; the independent causal magnitude remains to be proven. I recommend sauna use to men who have access to it as an adjunct, not a substitute, for the rest of this protocol.

PILLAR FOUR: CONNECT

Protocol Element 9 — The Relationship Layer (Days 91–365) Honesty Scale: 4 / Promising

I have saved this for last not because it is least important — the evidence suggests it carries as much cardiovascular weight as any intervention in this chapter — but because it is the layer men are most likely to skip if it appears first. Valtorta et al.’s 2016 meta-analysis in Heart (pooled HR for poor social relationships and incident coronary heart disease: 1.29, 95% CI 1.18–1.41) established social disconnection as an independent predictor of cardiovascular events with effect sizes comparable to traditional risk factors. The 2023 U.S. Surgeon General’s Advisory on loneliness and isolation identified cardiovascular disease as a downstream consequence of social disconnection and placed this formally in the clinical vocabulary.

The protocol recommendation is deliberately modest, because ambitious recommendations in this domain produce the least action. In the first 90 days of the protocol, one conversation counts. Not a relationship overhaul. Not joining a men’s group. One honest conversation with one person — physician, partner, friend, brother — in which you say something true about what the last year has cost you. That is the clinical intervention. It is free, takes 30 minutes, and has been shown in the social support literature to reduce inflammatory markers, lower cortisol, and improve sleep architecture. It is also the hardest thing in this entire protocol for most of the men I treat.

Tests to Order This Week

This is the measurement layer. Before any behavioral intervention, before any pharmacological conversation, you need this baseline. Print this list and bring it to your physician.

The Essential Panel (order at your next appointment or via direct-to-consumer lab if your physician declines):

1. ApoB — not LDL. ApoB counts the atherogenic particle number directly. The target is <90 mg/dL for low-risk men, <70 mg/dL for those with any established risk factor or CAC >0. If your lab doesn’t automatically include it, ask specifically.
2. Lp(a) — once in a lifetime, regardless of your LDL. If your Lp(a) is above 125 nmol/L, the entire risk conversation changes and we become more aggressive about everything else.
3. High-sensitivity CRP (hs-CRP) — the inflammatory substrate. Above 2 mg/L in a man with normal LDL warrants a statin conversation (see the JUPITER trial findings from Chapter 6). Below 1 mg/L is reassuring.
4. Fasting insulin and hemoglobin A1c — not just fasting glucose, which misses the pre-diabetic man with elevated insulin and normal glucose. Fasting insulin above 10 µIU/mL in a man with a normal fasting glucose means the pancreas is working very hard to maintain that normal glucose. That is the picture of insulin resistance.
5. Total and free testosterone with SHBG — free testosterone is the active fraction; total testosterone above 400 ng/dL can still represent functional hypogonadism if SHBG is high. Ask specifically for the free testosterone calculation.
6. Morning cortisol (8 a.m. serum) — the baseline assessment of your HPA axis. Elevated morning cortisol above 20 µg/dL in combination with suppressed testosterone and disturbed sleep is the cortisol-testosterone seesaw phenotype described in Chapter 8.
7. TSH — thyroid-stimulating hormone. Not routinely included in standard physicals. Subclinical hypothyroidism (TSH 4.5–10 mIU/L) is associated with diastolic dysfunction and arterial stiffness and affects 3–8% of men over 40.
8. Complete metabolic panel with liver enzymes — MASLD (metabolic dysfunction-associated steatotic liver disease) affects 42% of U.S. adults. Elevated ALT above 40 U/L is your first signal and requires follow-up imaging.
9. Comprehensive blood pressure measurement — not a single office reading, which misses the 22% of men who have normal office pressure and elevated ambulatory pressure (masked hypertension). If your office blood pressure is above 130/80, ask for a 24-hour ambulatory blood pressure monitor, or begin home blood pressure monitoring twice daily for two weeks.
10. CAC score referral — if you are over 40 with any cardiovascular risk factor. A coronary artery calcium scan costs $100–$150, takes 12 minutes, involves no contrast injection, and provides more actionable risk stratification than ten years of routine lipid panels.
11. STOP-BANG assessment for OSA — complete it before you leave the appointment.

Conversations to Have

With your physician: “I’ve been reading about cardiovascular risk in men my age, and I want to make sure we have a complete picture. Can we add ApoB, Lp(a), hs-CRP, fasting insulin, free testosterone with SHBG, and a morning cortisol to my next lab order? I’d also like to discuss whether a CAC score is appropriate for me, and complete a STOP-BANG screen today.”

That is the conversation. If your physician declines to order these tests without clinical justification, request a cardiology consultation. You are entitled to a complete workup. You are not required to accept a standard-of-care that was designed for the average patient, and you are not average.

With your partner: The conversation you have been not having. Not about health specifically — though that is useful — but about the gap between how you present and what you actually carry. The research on social support and cardiovascular recovery is clear: men who disclose health concerns to a trusted partner have better adherence to medical recommendations, lower cortisol awakening responses, and lower rates of delayed symptom presentation. Your partner has probably been waiting for this conversation for longer than you realize. You do not need to be vulnerable in a way that feels theatrical. You need to say one true thing about what the last year has been like.

With a male friend: The American Perspectives Survey found that only 30% of men had a private, personal conversation with a close male friend in the past week. If you are in the other 70%, the protocol recommendation is not to find a therapist. It is to call the person whose voice you haven’t heard in three months. You know who that is.

The 90-Day Checkpoints

Day 1–7: Make the physician appointment. Complete the STOP-BANG. Order the labs if possible before the appointment.

Day 8–30: Lab results returned. Physician conversation about findings. Begin Zone 2 cardio three times per week. Establish consistent wake time. If STOP-BANG positive, sleep study referral initiated.

Day 31–60: Resistance training twice per week begins. Sleep intervention active. If hs-CRP above 2 and CAC above 0, statin conversation underway. Begin IMST if blood pressure above 130 systolic.

Day 61–90: Review metrics: resting heart rate, blood pressure, sleep quality (subjective), energy. One honest conversation with one person — partner, friend, or physician — about what this 90-day process has actually been like.

Day 91: Re-assessment appointment. Repeat ApoB, hs-CRP, fasting insulin. Compare to baseline. Adjust the protocol with your physician based on findings.

Year 1: The annual cardiovascular review. Full panel. CAC re-scan if initial was between 1 and 99. Testosterone re-check if initially low. Sleep study if CPAP was initiated and adherence has been below four hours per night. Discussion of statin continuation and targets. And the question your physician should ask but probably won’t: how are the relationships?

Clinical Pearl: The single most important action in this protocol is also the simplest: get your numbers. ApoB. CAC score. Blood pressure properly measured. Testosterone with SHBG. Sleep study if you snore. You cannot intervene on what you have not measured. The entire protocol follows from that first conversation with your physician. Everything else in this chapter is what to do once you know.

Marcus came into my clinic at 49. He’d been training for a half-marathon for three months. He felt, by his account, the best he’d felt in years. His lipid panel looked fine — LDL of 108 mg/dL, HDL of 52. His blood pressure was 134/86, which his previous physician had attributed to “white coat effect.” We ordered the complete panel I’ve described above. His ApoB was 138 mg/dL. His CAC score was 210. His Lp(a) was 180 nmol/L — in the high-risk range. His fasting insulin was 14. He had no symptoms. He felt, by every metric he was measuring, excellent. He was not excellent. He was an asymptomatic man with multiple converging risk factors who had been told his cholesterol was fine and had believed it. He is now on a statin, his ApoB is 68, his Lp(a) is being monitored as the RNA therapeutics pipeline matures, and he completed his half-marathon six months after our first appointment. He also called his brother, whom he hadn’t spoken to in two years, the week after I told him about his calcium score. Those two things are not unrelated.

Permission: There is a version of this chapter that could feel like an indictment — a list of everything you haven’t done, a clinical inventory of your neglect. That is not how I am offering it. I am offering it the way I offer a protocol to any patient in my clinic: with the full expectation that you will implement it imperfectly, partially, and in your own sequence. Every single element in this chapter is available to you right now. Nothing requires a special credential, unusual financial resources, or a transformation of character. It requires one phone call, one blood draw, one honest conversation, and the willingness to let the numbers tell you what the numbers know. You have been running this body without a complete dashboard for years. This chapter is the dashboard. You are allowed to look at it.

What to Do This Week:

1. Schedule a physician appointment this week — specifically for a cardiovascular workup. When you call, tell the scheduler you want to discuss your cardiovascular risk factors and request a complete lab panel. Bring the list of tests above.
2. Complete the STOP-BANG questionnaire tonight. It takes 90 seconds. Score 3 or above means a sleep study is indicated — note that for your appointment.
3. Begin Zone 2 cardio this week — three sessions of 30 minutes of brisk walking, cycling, or swimming at a conversational pace. Not tomorrow. This week.

The protocol gives you the next ninety days. The next chapter is about what comes after — not as a different protocol, but as a different relationship to the man you are in the process of becoming.
