Myocardial Infarction Specialists in Janakpuri, Delhi

What is Myocardial Infarction?

Myocardial infarction, commonly known as a heart attack, occurs when blood flow to a part of the heart muscle is abruptly blocked, usually by a blood clot forming over a ruptured cholesterol plaque in a coronary artery. The resulting lack of oxygen causes heart muscle cells in the affected area to begin dying within minutes, making a heart attack a time-critical medical emergency where "time is muscle." It typically presents with sudden, severe chest pain, though presentation can be less typical in women, older adults, and people with diabetes. Rapid diagnosis through ECG and cardiac biomarker blood tests, followed by prompt restoration of blood flow, significantly improves survival and reduces permanent heart damage. Recovery involves cardiac rehabilitation and long-term management of underlying risk factors to prevent recurrence.

Causes of Myocardial Infarction

Most commonly caused by rupture of an atherosclerotic plaque within a coronary artery, triggering formation of a blood clot that suddenly blocks blood flow to part of the heart muscle. Underlying risk factors include coronary artery disease, high cholesterol, hypertension, diabetes, smoking, and obesity, all of which promote plaque formation and instability. Acute triggers can include intense physical exertion, severe emotional stress, cocaine use, and extreme cold exposure in susceptible individuals.

Symptoms of Myocardial Infarction

Sudden severe chest pain or pressure, pain radiating to the left arm, jaw, neck, or back, shortness of breath, cold sweats, nausea and vomiting, lightheadedness, sense of impending doom, in atypical presentations fatigue or indigestion-like discomfort

Treatment & Types of Myocardial Infarction in Janakpuri, Delhi

Immediate treatment focuses on restoring blood flow through emergency procedures such as percutaneous coronary intervention with stent placement or, when unavailable promptly, clot-dissolving thrombolytic medication. Ongoing medical therapy includes antiplatelet agents, beta-blockers, statins, and ACE inhibitors to reduce the risk of another event and support heart function recovery. Cardiac rehabilitation involving supervised exercise, dietary counselling, and risk factor management is recommended after the acute event to improve long-term outcomes.
