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 Chandigarh
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.
Heart attacks are classified as STEMI, involving complete blockage of a coronary artery and requiring the most urgent restoration of blood flow, or NSTEMI, involving partial blockage and typically less immediately dramatic ECG changes but still needing prompt treatment. They are also described as Type 1, from plaque rupture and clot formation, versus Type 2, from an oxygen supply-demand mismatch without plaque rupture, such as during severe anaemia or extreme physical stress.

Frequently Asked Questions
What does time is muscle mean for a heart attack?
It reflects that heart muscle cells begin dying within minutes of blood flow being blocked, so the faster blood flow is restored through procedures like angioplasty, the more heart muscle is preserved and the better the long-term outcome.
How do doctors tell STEMI and NSTEMI apart?
An ECG performed immediately on arrival distinguishes the two based on specific electrical changes, and this determines whether emergency clot-removal procedures are needed right away or whether treatment can be planned slightly less urgently.
Can women have different heart attack symptoms than men?
Yes, women, older adults, and people with diabetes more often experience atypical symptoms like fatigue or indigestion-like discomfort rather than classic severe chest pain, which can delay recognition and treatment.
What happens during cardiac rehabilitation after a heart attack?
It's a structured program of supervised exercise, dietary counselling, and risk factor management that helps the heart recover function and significantly reduces the risk of another cardiac event.
How can I reduce my risk of a second heart attack?
Taking prescribed medications like antiplatelets, beta-blockers, and statins consistently, along with managing blood pressure, cholesterol, and blood sugar and not smoking, substantially lowers the risk of recurrence.
