Heart Attack vs. Cardiac Arrest vs. Heart Failure: Know the Difference
5 Aug
Summary
- Heart failure is a condition where the heart pumps insufficient blood.
- A heart attack is muscle death due to a blocked coronary artery.
- Cardiac arrest occurs when the heart stops beating effectively.
Cardiovascular surgeon Dr. Kaushal Pandey recently emphasized the critical distinctions between heart attack, cardiac arrest, and heart failure, conditions often mistakenly used interchangeably. He explained that heart failure occurs when the heart fails to pump adequate blood, causing congestion, often due to weakened or stiffened heart muscle.
A heart attack, in contrast, is defined as the death of heart muscle tissue resulting from a blockage in a coronary artery. Cardiac arrest is characterized by the abrupt cessation of the heart's effective beating, leading to a lack of blood supply to vital organs.
These conditions, while distinct, are interconnected. A severe heart attack can lead to heart failure or even trigger cardiac arrest. However, each has unique causes, symptoms, and treatment protocols, underscoring the importance of accurate diagnosis for effective medical intervention.
