1 What is angina? (and how it differs from a heart attack) ▾

Angina basics

  • Angina = chest pressure, tightness, heaviness, or breathlessness caused by reduced blood flow to heart muscle.
  • Typical triggers: exertion, emotional stress, cold weather, or heavy meals. Improves with rest or nitroglycerin.
  • Stable angina: predictable pattern under similar effort. Unstable angina: new, worsening, or at rest — treat as urgent.

Heart attack (acute)

  • Severe or persistent chest pressure, often with sweating, nausea, shortness of breath, weakness, or faintness.
  • May radiate to jaw, neck, back, shoulders, or arms. Can be “silent” or atypical in older adults and women.
  • Emergency: symptoms lasting >5 minutes, or sudden and severe. Call emergency services immediately.
2 Red flags — when to call for help now ▾
  • Severe chest pressure or pain that does not improve with rest within 5 minutes.
  • Chest discomfort with shortness of breath, fainting, cold sweat, nausea, or sudden weakness/confusion.
  • New chest pain at rest, or rapidly worsening pattern of pain.
Call emergency services immediately for the above symptoms. Do not drive yourself.
3 Other causes of chest pain (not only the heart) ▾

Chest discomfort has many causes. This table helps you think about patterns; your clinician will decide next steps.

CategoryCluesNotes
Heart (angina)Pressure/tightness with exertion, cold, stress; better with rest/nitroOften radiates to arm/jaw; may be “atypical” in seniors
Heart (attack)Severe, persistent; sweating, nausea, breathlessnessEmergency — call immediately
Reflux (GERD)Burning after meals/lying downMay improve with antacids; can mimic heart pain
Muscle/jointTender to touch or certain movementsLocal soreness, recent strain
LungsPain with deep breath, cough, feverPneumonia, pleurisy, pulmonary embolism (urgent)
Anxiety/panicChest tightness, fast heart rate, tremblingClinician should rule out heart/lung causes first
4 Common triggers & how to use nitroglycerin safely ▾

Typical triggers

  • Walking uphill or against the wind, hurrying, or carrying weight.
  • Cold exposure or heavy meals.
  • Emotional stress or poor sleep.

Nitroglycerin instructions

  1. Sit down. Place 1 tablet under the tongue (or use spray) at the start of chest pain.
  2. Wait 5 minutes. If pain remains, take a 2nd dose and call emergency services.
  3. Up to 3 doses total, 5 minutes apart, while waiting for help.

Safety: Do not use nitroglycerin with medicines for erectile dysfunction (sildenafil, tadalafil, vardenafil) within the time window your clinician advises — dangerous blood pressure drop.

5 How clinicians evaluate chest pain ▾
  • ECG (electrocardiogram) to look for ischemia or prior injury.
  • Blood tests (troponin) to check for heart muscle damage.
  • Stress testing (treadmill, echo, or nuclear) for effort-related symptoms.
  • CT coronary angiography to view coronary arteries non-invasively in selected cases.
  • Cardiac catheterization (invasive angiography) when high risk or treatment is likely.

Your history, exam, and risk factors guide which test is best.

6 Treatment overview (medicines, procedures, lifestyle) ▾

Medicines

  • Antianginals: beta-blockers, calcium-channel blockers, long-acting nitrates, ranolazine.
  • Risk reduction: statins for cholesterol; blood-pressure and diabetes control; antiplatelet therapy when indicated.

Procedures

  • Stent (PCI) or bypass surgery when blockages are significant or symptoms persist despite medicines.

Daily habits

  • Warm-up before activity; pace uphill; avoid heavy lifting right after meals.
  • Low-salt, heart-friendly meals; no smoking; regular, gentle activity.
  • Carry nitroglycerin if prescribed; keep a symptom log for your visit.
7 Senior-friendly daily safety plan ▾
  • Morning check-in: how you feel, sleep quality, swelling, weight if advised.
  • Activity pacing: break tasks into smaller steps; rest as needed; avoid sudden sprints.
  • Temperature: in cold weather, warm up indoors before walking outside; cover mouth/nose.
  • Meals: smaller portions; avoid heavy meals before exertion; limit alcohol as advised.
  • Medication routine: pill box labeled by time; keep nitroglycerin accessible and not expired.
  • Appointment prep: bring a short question list and your symptom/angina log.
8 Medication safety & interactions ▾
  • Do not combine nitroglycerin with erectile-dysfunction medicines within the advised time window.
  • Report dizziness, swelling of ankles, or extreme fatigue to your clinician.
  • Do not stop heart medicines suddenly unless advised.
9 FAQs ▾

Can angina happen without chest pain?

Yes. In older adults and people with diabetes, shortness of breath, fatigue, or jaw/arm discomfort may be the main symptom.

How fast should nitroglycerin work?

Relief often begins within 1–3 minutes. If pain persists after 5 minutes, take another dose and call emergency services.

Will a normal ECG rule out heart problems?

Not always. Many people with angina can have a normal ECG at rest; further testing may be needed based on your symptoms and risk.
