Chest Pain in Women: Heart, Anxiety, Perimenopause, or Musculoskeletal? A Cardiologist's Differential

She has had chest pain for four months. Three physicians have told her three different things: it is anxiety; it is acid reflux; it is probably the costochondritis they found on physical exam. She has had two ECGs, both normal. She has not had a troponin, a stress test, or a rhythm monitor.

The clinical problem is not that these physicians were wrong about every possibility. The problem is that each physician closed the differential at the first plausible diagnosis without completing the workup that would confirm it or rule out cardiac causes with reasonable certainty. A woman with chest pain has several possible causes simultaneously. Confirming one does not eliminate the others.

The complete differential for women’s chest pain

The seven categories of chest pain each require different testing and carry different urgency.

Category 1: Acute coronary syndrome (ACS)

ACS, unstable angina, NSTEMI, or STEMI , is the highest-acuity cause and requires immediate evaluation. Women’s ACS presentations are more likely than men’s to include fatigue, nausea, back pain, and jaw pain without classic crushing chest pressure. High-sensitivity troponin (with repeat at 3 hours), ECG, and urgent cardiology evaluation are the appropriate response to suspected ACS. 5 / Solid

Category 2: Stable angina, ANOCA, and microvascular coronary dysfunction

Stable exertional chest pain or pressure that comes on with physical or emotional stress and resolves with rest may represent stable coronary artery disease with obstructive plaque, or ANOCA (Angina with Non-Obstructive Coronary Arteries), where the small coronary arterioles are dysfunctional without obstructive plaque visible on angiography. Approximately 50-60% of women evaluated for ANOCA have measurable microvascular coronary dysfunction on physiological testing.

Women with this pattern, exertional heaviness, pressure, or dyspnea, normal resting ECG, perhaps a normal angiogram , are not negatively worked up. They have the right clinical picture for ANOCA. Stress imaging with coronary flow reserve assessment (PET or cardiac MRI) is the next appropriate test, not reassurance. 5 / Solid

Category 3: Coronary vasospasm

Vasospastic (Prinzmetal) angina produces chest pain typically at rest, often in the early morning hours or overnight, sometimes associated with ST elevation on ECG during the episode, but the artery looks completely normal on angiography performed after the spasm resolves. Women are affected disproportionately. The diagnosis requires either ECG documentation of an acute episode or acetylcholine provocation testing during cardiac catheterization.

A woman with rest chest pain, nocturnal pain, or pain on awakening that does not clearly correlate with exertion has vasospasm on her differential until it is ruled out.

Category 4: SCAD (Spontaneous Coronary Artery Dissection)

SCAD is an arterial wall tear, not plaque rupture, and accounts for approximately 35% of heart attacks in women under 50. SCAD presents with acute chest pain, elevated troponin, and ECG changes. It may look like a standard NSTEMI on initial presentation. The distinction matters because management is opposite: stenting is generally contraindicated in SCAD, whereas it is standard care for plaque-based ACS. OCT imaging during catheterization identifies SCAD morphology that standard angiography can miss.

Category 5: Musculoskeletal chest pain

Musculoskeletal causes are the most common non-cardiac cause of chest pain in the general population. Costochondritis (inflammation at the costochondral junction), rib stress, intercostal muscle strain, and thoracic spine-referred pain all produce chest wall discomfort.

Features that suggest musculoskeletal origin:

• Pain reproduced by pressing on the chest wall, particularly at the costochondral junction (where ribs meet sternum)
• Pain that varies with movement, position, or breathing
• Sharp or knife-like quality localized to a small, identifiable point
• No association with exertion or stress
• No radiation to jaw, arm, or back

The limitation of this category: musculoskeletal chest pain is a clinical diagnosis of inclusion. Reproducible tenderness is a finding, not a diagnosis that excludes other causes.

Category 6: Gastrointestinal causes

GERD (gastroesophageal reflux disease) and esophageal spasm can produce chest pain that is indistinguishable from cardiac pain by symptoms alone. Esophageal spasm in particular can produce severe, crushing, substernal chest pain that radiates to the back and may be relieved by nitroglycerin (because nitroglycerin relaxes esophageal smooth muscle as well as coronary smooth muscle).

Features suggesting GI origin: association with meals or lying down after eating, relief with antacids, heartburn or regurgitation symptoms, worsening with spicy or fatty food.

The critical point: GI and cardiac causes frequently coexist. GERD does not reduce cardiovascular risk. A woman with documented GERD who develops new-onset chest pain that is different in character from her usual reflux symptoms needs cardiac evaluation. 5 / Solid

Category 7: Perimenopausal and autonomic chest pain

In women 40-55, a distinct category of chest pain, pressure, tightness, or racing heart sensation associated with hot flashes, or occurring spontaneously without a clear precipitant , reflects the autonomic dysregulation of perimenopause.

Hot flashes are sympathetic nervous system events with real cardiovascular effects: heart rate rises 7-15 bpm, blood pressure transiently shifts, and many women experience concurrent pressure or tightness sensations. For women having 8-12 hot flashes per day, this is 8-12 acute sympathetic events with associated chest sensations.

This category is real but is also a diagnosis of exclusion, the autonomic-origin chest discomfort of perimenopause should not be the working diagnosis until cardiac causes have been evaluated with appropriate specificity.

Additional causes that complete the differential

The seven categories above address the most common causes. Three additional diagnoses must be on the differential in any woman presenting with chest pain.

Pericarditis

Inflammation of the pericardium produces chest pain that is characteristically sharp, pleuritic (worsening with inspiration), and positional — worse when lying flat, improved when sitting forward and leaning toward the knees. The pain may radiate to the left shoulder or trapezius ridge. The resting ECG in acute pericarditis shows diffuse ST elevation in a saddle-shaped pattern across most leads, which distinguishes it from the regional ST elevation of ACS. A friction rub on auscultation is pathognomonic but often absent.

Pericarditis in women under 50 is often viral or idiopathic, follows a recent febrile illness in most cases, and has a favorable prognosis with early, appropriate treatment (NSAIDs combined with colchicine, which reduces the rate of recurrent pericarditis by approximately 50% compared to NSAIDs alone). However, the diagnosis requires exclusion of myocarditis (elevated troponin, cardiac MRI) and cardiac tamponade (pericardial effusion on echocardiography). A woman with sharp positional chest pain after a recent viral illness does not have costochondritis until pericarditis has been evaluated with ECG, echocardiography, and, where troponin is elevated, cardiac MRI to assess for concurrent myopericarditis. 5 / Solid

Pulmonary embolism

PE produces pleuritic chest pain (sharp, breathing-related), dyspnea, and in the setting of large or submassive PE, hypotension, right heart strain, and syncope. The classic triad of dyspnea, pleuritic chest pain, and hemoptysis is present in only a minority of patients. Women on combined oral contraceptives, postpartum women, and women with prolonged immobility have elevated PE risk. D-dimer is the appropriate initial test in low-to-intermediate pretest probability; CT pulmonary angiography confirms the diagnosis. PE requires explicit clinical consideration because it is frequently missed and carries high mortality if anticoagulation is delayed.

Anxiety and panic disorder

Panic attacks produce genuine physical chest pain — pressure, tightness, or sharp pain — alongside palpitations, dyspnea, derealization, and fear of dying. The symptoms are real, not imagined. The clinical problem is the sequence of evaluation: anxiety is a diagnosis of exclusion in chest pain, not a provisional diagnosis given at presentation. Attributing chest pain to anxiety before completing appropriate cardiac evaluation leads to missed MINOCA, missed vasospasm, and missed ANOCA in women — all of which produce symptoms that overlap with panic disorder.

After a complete, appropriate cardiac workup is negative, anxiety and panic disorder are legitimate and treatable diagnoses. Before that workup, anxiety is a working hypothesis, not a conclusion.

The symptoms that override the differential

Regardless of what else is present in the history, these presentations require immediate emergency evaluation:

Chest pain with diaphoresis (sweating): Sympathetic activation from myocardial ischemia. No diagnostic algorithm applies first, evaluation first.

Chest pain with syncope or near-syncope: Arrhythmia, significant hemodynamic compromise, or pulmonary embolism until proven otherwise.

Chest pain with acute-onset shortness of breath: Pulmonary embolism, tension pneumothorax, or acute decompensation. Needs immediate evaluation.

Chest pain radiating to jaw, both arms, or the back between the shoulder blades: Cardiac ischemia or aortic dissection.

Chest pain described as “the worst of my life” with sudden onset: Aortic dissection, tension pneumothorax, or massive PE.

Chest pain in someone with prior MI, known CAD, heart failure, or prior SCAD: The threshold for urgent evaluation is lower, not higher, with cardiac history.

The standard workup is incomplete for women

The standard chest pain workup, resting ECG and a single troponin , has important limitations in women. 5 / Solid

High-sensitivity troponin assays improve detection, but a single negative value at one time point rules out evolving myocardial injury only approximately 75% of the time. Serial measurement at 0 and 3 hours substantially improves the negative predictive value.

Resting ECG is a 10-second snapshot. Vasospasm that has resolved, arrhythmias that are paroxysmal, and microvascular dysfunction that requires physiological stress to manifest are all invisible on a resting ECG.

A complete workup for persistent or unexplained chest pain in women:

1. High-sensitivity troponin at 0 and 3 hours
2. Resting ECG
3. Lipid panel with Lp(a)
4. 14-30 day ambulatory rhythm monitoring (not 24-hour Holter, which misses intermittent arrhythmia)
5. Stress imaging with coronary flow reserve assessment. PET or cardiac MRI with adenosine stress, not exercise ECG alone
6. If angiogram performed and non-obstructive: coronary physiology testing (CFR, IMR) and provocative vasospasm testing before declaring the workup negative

Matching the test to the clinical picture

Not every woman with chest pain needs the same workup. The clinical pattern guides which tests to prioritize.

Acute onset with diaphoresis, radiation, or hemodynamic change: High-sensitivity troponin at 0 and 3 hours, resting ECG, and immediate cardiology consultation. This is an emergency presentation; testing sequence follows clinical urgency.

Exertional pattern — symptoms with activity or emotional stress, relieved by rest: Stable coronary artery disease and ANOCA are the primary considerations. Stress imaging with coronary flow reserve assessment is the appropriate next test, not resting ECG or standard exercise treadmill testing. Stress PET or adenosine cardiac MRI detects both obstructive disease and microvascular dysfunction. Exercise ECG has poor sensitivity for the type of ischemia most common in women.

Rest or nocturnal pattern — symptoms occurring at rest, overnight, or on waking: Vasospasm rises to the top of the differential. A 14-30 day event recorder captures the ECG during symptomatic episodes. Holter monitoring over 24 hours is inadequate for intermittent symptoms. If structural workup and ambulatory monitoring are unrevealing, provocative acetylcholine testing during catheterization directly confirms or excludes vasospasm.

Palpitation-associated chest symptoms: The palpitation is the signal to prioritize rhythm monitoring. Supraventricular tachycardia, atrial fibrillation, and frequent premature ventricular contractions can all produce chest pressure during episodes. A 30-day event monitor with patient-activated recording captures these events in their clinical context.

Pleuritic or positional pattern — worsens with breathing or lying flat: Pericarditis and pulmonary embolism are the first considerations. ECG (looking for diffuse saddle-shaped ST changes), echocardiography (pericardial effusion), and D-dimer should precede reassignment to musculoskeletal causes.

Reproduced by chest wall pressure alone: Costochondritis is supported. But costochondritis is only the conclusion after ruling out concurrent cardiac cause, not before it. A woman can have both. The physical finding confirms the musculoskeletal component; it does not dismiss the cardiac question. 5 / Solid

When the workup is genuinely complete and negative

A thorough, appropriate cardiac workup for a woman with chest pain looks like this: normal high-sensitivity troponin at 0 and 3 hours, normal serial ECGs, stress imaging with coronary flow reserve assessment that shows no ischemia and normal flow reserve, 14-30 day rhythm monitoring without significant arrhythmia, and — if angiography was performed — normal coronary physiology and negative vasospasm provocation testing.

When this full sequence is complete and negative, the clinician and patient can have a genuinely informed conversation about non-cardiac causes. In perimenopausal women, the autonomic dysfunction of perimenopause itself is then a supportable diagnosis for episodic symptoms. Hot flash-related sympathetic activation, sleep-disruption driven autonomic instability, and the chest discomfort that accompanies palpitation episodes from perimenopausal hormonal fluctuation are all real, treatable, and appropriate explanations once cardiac has been excluded with appropriate specificity.

Anxiety and panic disorder, similarly, are appropriate working diagnoses after thorough cardiac exclusion — not before. And the treatment for panic-disorder chest symptoms (CBT, SSRI, breathing techniques) is different from and complementary to the treatment for perimenopausal vasomotor symptoms (MHT, lifestyle modification, targeted autonomic management). A woman deserves to know which she has, or whether she has both.

The four-month chest pain case that opened this article — three physicians, three different diagnoses, no stress imaging, no troponin — is not a complete workup. Each clinician may have been correct about one component of her presentation. None had done the testing that would confirm their diagnosis or exclude a cardiac cause. That is the gap this article addresses.

Language for the next appointment

If you have chest pain and have been told the workup is negative:

“Can you confirm what testing has been completed? I would like to know whether I have had stress imaging with coronary flow reserve assessment, extended ambulatory rhythm monitoring for 14 or more days, and Lp(a) measured.”

“My resting ECG is normal. I understand that a normal resting ECG does not rule out microvascular dysfunction or vasospasm. Has that been evaluated?”

“I was told my angiogram was normal. I would like to know whether coronary physiology testing was performed during the catheterization, or whether that is recommended given my ongoing symptoms.”
