Heart Attack (Myocardial Infarction) — Symptoms, Causes & Treatment
Quick Summary: A heart attack occurs when blood flow to part of the heart muscle is blocked, usually by a clot in a coronary artery. Every minute of delay causes more heart damage. If you or someone near you has chest pain with sweating, breathlessness or arm pain — call 071-22980073 immediately for Hope Hospital's 24/7 cardiac emergency.
What is a Heart Attack?
A heart attack, also called myocardial infarction (MI), happens when the blood supply to a part of the heart muscle is suddenly cut off — usually by a blood clot in a narrowed coronary artery. Without oxygen-rich blood, the heart tissue starts to die within minutes. Rapid treatment in the first hour (the "golden hour") can save lives and minimize permanent damage.
Heart attack is the leading cause of death in India. Recognizing the symptoms and acting fast — by calling an ambulance and getting to a NABH-accredited hospital with a 24/7 Cath Lab like Hope Hospital — dramatically improves survival.
Warning Signs and Symptoms
Symptoms can develop suddenly or appear gradually over hours. Classic warning signs include:
- Chest pain or pressure: Often described as squeezing, fullness or a heavy weight on the chest, lasting more than a few minutes
- Pain radiating outward: To the left arm, jaw, neck, back, or upper abdomen
- Shortness of breath: With or without chest discomfort
- Cold sweat: Sudden, clammy perspiration
- Nausea, vomiting or indigestion-like discomfort
- Lightheadedness or sudden dizziness
- Unusual fatigue: Especially in women, sometimes days before the attack
Women, diabetics and the elderly may have atypical symptoms — like jaw pain, back pain, indigestion, or unexplained fatigue — without classic chest pain. Do not dismiss these as gas or stress.
Causes and Risk Factors
The underlying cause is usually coronary artery disease (CAD) — a buildup of cholesterol plaques inside the coronary arteries. A plaque can rupture, causing a blood clot that blocks the artery.
Major Risk Factors
- High blood pressure (hypertension)
- High cholesterol (LDL)
- Diabetes
- Smoking and tobacco use
- Obesity and abdominal fat
- Sedentary lifestyle
- Family history of early heart disease
- Age: Men over 45, women over 55
- Chronic stress, poor sleep
Diagnosis
At Hope Hospital's Zion Cardiac Hospital, emergency cardiac evaluation is done within minutes of arrival:
- ECG (Electrocardiogram): Detects abnormal heart rhythms and signs of MI within seconds
- Cardiac biomarkers (Troponin): Blood test confirming heart muscle damage
- Echocardiogram: Ultrasound showing heart pumping function
- Coronary angiography: Cath Lab imaging that finds the exact blockage
- Chest X-ray and bloodwork
Emergency Treatment
Primary Angioplasty (PCI)
The gold-standard treatment for a heart attack. A thin catheter with a balloon and stent is threaded through an artery in the wrist or groin to the blocked coronary artery. The balloon opens the artery and the stent keeps it open. Hope Hospital's Cath Lab is staffed 24/7 for emergency PCI.
Thrombolytic Therapy
Clot-busting medications given intravenously when angioplasty cannot be performed within the golden hour.
Coronary Artery Bypass Grafting (CABG)
Open-heart surgery that creates new pathways around blocked arteries using grafts from the leg, arm or chest. Preferred when there are multiple severe blockages or when angioplasty is unsuitable.
Medications
- Antiplatelets (aspirin, clopidogrel, ticagrelor)
- Anticoagulants (heparin)
- Beta-blockers, ACE inhibitors, statins
- Pain relief (morphine if needed)
Recovery and Cardiac Rehabilitation
After a heart attack, structured cardiac rehabilitation helps recover strength and prevent another event:
- Supervised exercise programs
- Lifestyle counselling (diet, smoking cessation, stress management)
- Long-term medication adherence
- Regular follow-up with the cardiology team
- Blood pressure, blood sugar and cholesterol monitoring
Prevention
- Quit smoking and tobacco — the single biggest controllable risk
- Eat a heart-healthy diet (fruits, vegetables, whole grains, less salt and saturated fat)
- Exercise at least 30 minutes a day, 5 days a week
- Maintain healthy weight, waist circumference under 90 cm (men) / 80 cm (women)
- Control blood pressure, blood sugar and cholesterol
- Manage stress and sleep 7–8 hours
- Annual heart checkup after age 40, especially if you have risk factors
When to Seek Emergency Care
Call 071-22980073 or rush to Hope Hospital immediately if you or someone near you has:
- Chest pain or pressure lasting more than 5 minutes
- Chest discomfort with sweating, breathlessness or nausea
- Pain radiating to the arm, jaw or back
- Sudden severe weakness or fainting
- Unexplained, persistent shortness of breath
Do NOT drive yourself — call an ambulance so emergency care can begin en route.
