What is Unstable Angina?

Unstable angina is a form of acute coronary syndrome in which sudden and severe impairment of coronary blood flow occurs because of atherosclerotic plaque rupture or thrombus formation.

Unlike stable angina, it may begin at rest, is more severe than before, or follows a progressively worsening course. The biomarker of myocardial injury, troponin, is not elevated; this is what distinguishes unstable angina from NSTEMI.

Unstable angina is a serious and potentially life-threatening condition that requires urgent cardiology evaluation and monitoring — a genuine medical emergency.

Symptoms

Chest pain or pressure that begins at rest
Pain that is more severe than before and triggered by less exertion
Anginal pain lasting more than 20 minutes
Chest pain that wakes the patient from sleep at night
Pain accompanied by sweating, nausea, or pallor
Partial response — or no response — to nitrates

Risk Factors

Known coronary artery disease
A prior diagnosis of stable angina
Hypertension, diabetes, and hyperlipidemia
Smoking and a sedentary lifestyle
Advanced age and male sex

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • If chest pain begins at rest, go to the emergency department immediately
  • For prompt evaluation if the pattern of angina changes or worsens
  • In known cardiac patients, any change in pain character
  • If there is no response to nitrate therapy

Treatment Methods

01
Monitoring in the emergency department with ECG and serial troponin
02
Antiplatelet therapy (aspirin plus clopidogrel) and anticoagulation
03
Symptom control with beta-blockers, nitrates, and morphine
04
Early or urgent coronary angiography and intervention when indicated
05
Intensive statin therapy and long-term medical treatment

Heart Palpitations

Kardiyoloji

Palpitations are usually due to benign causes, but underlying cardiac rhythm disorders must be ruled out.

Heart Valve Diseases

Kardiyoloji

Valve stenosis or regurgitation increases the workload of the heart and, over time, can lead to heart failure.

Aortic Aneurysm

Kardiyoloji

Aortic aneurysms are often silent; early diagnosis allows treatment before rupture (a life-threatening tear).
