Cardiovascular disease (CVD) is the leading cause of premature mortality worldwide and represents a rapidly growing health challenge in Bangladesh. Early symptom recognition, timely first aid, and rapid transport to a cath-lab-equipped cardiac center during the “Golden Hour” can mean the difference between full recovery and irreversible heart damage.
1. Recognizing the Warning Signs of a Heart Attack (Myocardial Infarction)
Heart attack symptoms do not always present as sudden, dramatic collapses. Many individuals experience gradual onset or atypical symptoms:
Classic Symptoms:
- Central Chest Pressure / Pain: A heavy, squeezing, or crushing sensation in the center of the chest lasting more than a few minutes.
- Radiating Pain: Pain or aching sensation spreading to the left shoulder, left arm, neck, jaw, back, or upper stomach.
- Shortness of Breath (Dyspnea): Difficulty breathing, with or without chest discomfort.
- Cold Sweats & Clammy Skin: Sudden profuse sweating accompanied by lightheadedness or dizziness.
Atypical Symptoms in Women, Elderly & Diabetic Patients:
Diabetic and elderly patients may experience a “silent heart attack” without severe chest pain, presenting only with sudden profound weakness, unexplained nausea, vomiting, dizziness, or sudden breathlessness.
2. Immediate First Aid Protocol During a Suspected Heart Attack
- Call for Emergency Transport Immediately: Dial 999 or call the nearest dedicated cardiac hospital ambulance hotline. Do not wait to see if symptoms pass.
- Rest the Patient: Have the patient sit comfortably on the floor with their back supported (the “W” position) and loosen any tight clothing. Do not allow them to walk or exert effort.
- Aspirin Administration (If Not Allergic): If available and the patient is conscious and has no known aspirin allergy or active internal bleeding, have them chew and swallow one soluble 300 mg Aspirin tablet (Disprin / Ecosprin 300mg) to inhibit further blood clot progression.
- Sublingual Nitroglycerin (If Prescribed): If the patient is a known cardiac patient with a prescribed Nitroglycerin spray or sublingual tablet (e.g., Nitromint), administer 1 puff under the tongue while the patient is seated.
3. Key Specialized Cardiac Hospitals in Bangladesh
- National Institute of Cardiovascular Diseases (NICVD), Dhaka: The premier specialized government cardiac center offering 24/7 emergency primary PCI (angioplasty) and cardiac ICU care.
- National Heart Foundation Hospital & Research Institute, Mirpur: Renowned specialized center for advanced cardiac surgery, stenting, and preventive cardiology.
- Evercare Hospital, Dhaka & Chattogram: Comprehensive 24/7 emergency interventional cardiology and cardiac surgery departments.
- United Hospital Heart Centre, Gulshan: Advanced cardiac surgical and coronary care units.
- Ibrahim Cardiac Hospital & Research Institute (Shahbagh): Specialized tertiary cardiac hospital associated with BIRDEM.
4. Lifelong Heart Health Preservation Tips
- Know Your Numbers: Regularly monitor your Blood Pressure (target < 120/80 mmHg), Fasting Glucose (< 100 mg/dL), and LDL Cholesterol (< 100 mg/dL).
- Complete Tobacco Cessation: Smoking and smokeless tobacco (zarda, gul, sada pata) constrict coronary arteries and dramatically increase clot formation.
- Heart-Healthy Nutrition: Emphasize omega-3 rich fish (ilish, rui, katla), colorful vegetables, and nuts while eliminating trans fats.
