Myocardial ischemia induces cardiac dysfunction, resulting in insufficient oxygen supply to peripheral tissues and mismatched energy production during exercise .

Does myocardial ischemia increase cardiac output?

What is normal cardiac index?

What does ischemia feel like?

What are symptoms of myocardial ischemia? The most common symptom of myocardial ischemia is angina (also called angina pectoris). Angina is chest pain that is also described as chest discomfort, heaviness, tightness, pressure, aching, burning, numbness, fullness, or squeezing. It can feel like indigestion or heartburn .

Can myocardial ischemia be reversed?

Generally, if the patients received timely and accurate diagnosis and treatment, the ischemia can be reversed and a favorable prognosis could be expected. Otherwise, reversible myocardial ischemia may develop into myocardial infarction, which is irreversible and the prognosis may be poor.
