Clinical manifestations of myocardial insufficiency

Myocardial ischemia generally refers to myocardial ischemia. Clinical manifestations of myocardial ischemia include precordial pain, arrhythmia, dyspnea, etc.

1. Patients with precordial pain

cause myocardial ischemia due to coronary artery stenosis, reduced coronary blood flow or increased myocardial oxygen consumption, resulting in precordial pain symptoms. Pain can radiate to the shoulder, back or upper limbs.

2. Patients with arrhythmia

cause cardiac conduction system abnormalities due to myocardial ischemia, resulting in irregular heartbeat, too fast or too slow.

3. Patients with dyspnea

cause cardiac ejection function to weaken due to myocardial contractility, resulting in pulmonary tissue congestion, resulting in dyspnea.
