The terms 'cardiac arrest' and 'heart attack' are often used interchangeably, but they refer to two distinct medical emergencies with different causes and treatments. Both conditions are life-threatening and require immediate medical attention. Here, it is important to note that both emergencies are linked to Coronary Heart Diseases (CHD), which are responsible for 1 in every 3 deaths across the world. How Is A Heart Attack Different From A Cardiac Arrest? Heart Attack (Myocardial Infarction)A heart attack occurs when blood flow to a part of the heart muscle is blocked, typically by a blood clot in a coronary artery. This blockage prevents oxygen-rich blood from reaching that part of the heart muscle, causing damage or eventual death of that muscle tissue. Common symptoms include chest pain or discomfort, shortness of breath, nausea, sweating, and pain in the arm, back, or jaw. Symptoms can vary and may be less obvious in some individuals.Treatment for a heart attack often involves medications to dissolve the clot, restore blood flow, or prevent further clots, along with procedures like angioplasty or stenting. Lifestyle changes and cardiac rehabilitation are also recommended for recovery.Cardiac ArrestCardiac arrest occurs when the heart suddenly stops beating effectively due to an electrical malfunction in the heart. This leads to a loss of heart rhythm (arrhythmia), such as ventricular fibrillation or ventricular tachycardia, and prevents the heart from pumping blood to the rest of the body.Symptoms include sudden collapse, loss of consciousness, and absence of pulse or breathing. Cardiac arrest often occurs without warning and is an immediate medical emergency.Immediate treatment involves cardiopulmonary resuscitation (CPR) and defibrillation (using an automated external defibrillator or AED) to restore a normal heart rhythm. Prompt medical intervention is crucial for survival and recovery.ASPECTCardiac ArrestHeart AttackDefinitionSudden loss of heart function due to an electrical malfunctionBlockage of blood flow to a part of the heart muscle due to a blocked arteryCauseElectrical malfunction in the heart's rhythm (arrhythmia) Plaque buildup in the coronary arteries (atherosclerosis)SymptomsSudden collapse, loss of consciousness, no pulse, no breathing Chest pain or discomfort, shortness of breath, nausea, sweating, pain in arm or jawOnsetImmediate and abrupt; occurs suddenly without warning Gradual; may start with mild symptoms that worsen over timeImmediate TreatmentCardiopulmonary resuscitation (CPR) and defibrillation (if needed) Medication to dissolve clots, angioplasty, or stent placement; sometimes surgeryLong-Term ManagementFocus on addressing the underlying cause of arrhythmia, such as implantable defibrillators or medication Lifestyle changes, medications, and possible surgical interventions to manage coronary artery diseasePreventionRegular cardiovascular check-ups, managing risk factors, and addressing arrhythmias Healthy diet, regular exercise, managing cholesterol and blood pressure, quitting smokingPrognosisHigh risk of sudden death if not treated immediately; survival often depends on prompt intervention Varies; many people recover with treatment, though heart damage can occur if not treated promptlyHow Can You Prevent Heart EmergenciesBoth heart attack and cardiac arrest can be caused due to Coronary or ischemic heart disease (CHD). Therefore, it is pivotal to maintain good heart health. Following are the precautionary tips you can use to prevent CHD, as per World Health Organization (WHO).Adopt a Heart-Healthy Diet: Focus on a diet rich in fruits, vegetables, whole grains, legumes, and nuts. Reduce intake of salty meats, processed foods, and sugary snacks. Opt for natural seasonings like calamansi juice and vinegar instead of high-sodium condiments, and drink water instead of sweetened beverages.Manage Your Weight: Achieve and maintain a healthy weight by aiming for a BMI below 25 and reducing central obesity. Cutting 500 calories from your daily intake can help you lose about half to one kilogram per week.Increase Physical Activity: Aim for at least 150 minutes of moderate exercise per week, such as brisk walking or gardening. Regular physical activity helps manage blood pressure, cholesterol, and weight.Avoid Tobacco: Refrain from smoking and exposure to second-hand smoke. Quitting tobacco reduces your risk of heart disease significantly over time.Limit Alcohol Consumption: Although occasional drinking is common, avoid alcohol entirely to minimize cardiovascular risk. There is no safe level of alcohol consumption for heart health.Monitor Blood Pressure and Sugar Levels: Regularly check your blood pressure and blood sugar with a healthcare provider. Unchecked high blood pressure can damage your heart. If diagnosed with hypertension or diabetes, adhere to your treatment plan and involve your loved ones in your health journey.
