Comparing Heart Attack, Heart Failure And Cardiac Arrest

Heart Attack (Myocardial Infarction):
A heart attack happens when the blood flow to the heart is literally blocked, thereby causing damage to the heart muscle. This can lead to chest pain, shortness of breath, and potentially life-threatening complications.

Heart Failure:
Heart failure occurs when the heart is unable to pump enough blood in order to meet the body's needs. This can be due to a heart attack, high blood pressure, or other conditions that weaken the heart. Heart failure can actually cause fatigue, swelling, and shortness of breath.

Cardiac Arrest: Cardiac arrest happens when the heart suddenly stops functioning or beating effectively. This can be life-threatening if not treated promptly. Cardiac arrest can be caused by a heart attack, electrical disturbances in the heart, or other medical conditions.

Here’s a simple explanation of what it shows and treatment to each:

❤️ Heart Attack
• What it is: A blockage in a blood vessel supplying the heart.
• What happens: Blood can’t reach part of the heart muscle, so that part gets damaged, but the heart is still beating.
• Common signs: Chest pain, sweating, nausea.
• Treatment: Medicines, stents, or surgery to restore blood flow.

⚡ Cardiac Arrest
• What it is: A sudden electrical problem in the heart.
• What happens: The heart stops beating suddenly, and the person may collapse.
• Signs: No pulse, no breathing, unconsciousness.
• Treatment: Immediate CPR and defibrillation (AED). This is a medical emergency.

💙 Heart Failure
• What it is: A weakened heart that cannot pump blood well.
• What happens: Blood and fluid back up in the body, causing congestion.
• Common signs: Shortness of breath, swollen legs, tiredness.
• Treatment: Medications like diuretics and ACE inhibitors, plus lifestyle care.

🗣📝 Key difference to remember:
• Heart attack: Blocked blood flow
• Cardiac arrest: Heart stops suddenly
• Heart failure: Heart is weak but still beating
