Heart attacks are commonly linked to blocked arteries, but in some cases, they can occur even when the arteries are clear. These are known as non-obstructive heart attacks. Tap to know the surprising reasons behind these heart attacks.
Coronary Artery Spasm
Also known as vasospastic angina, this occurs when a coronary artery suddenly tightens or has spasms, reducing the blood flow to the heart.
MINOCA
MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries) refers to a heart attack without significant blockage, often due to small vessel diseases, blood clots, or spasms.
Small Vessel Disease
When the tiny arteries in the heart get damaged, it can reduce the blood flow and trigger a heart attack even when major arteries are clear.
SCAD
SCAD (Spontaneous Coronary Artery Dissection) involves a tear in a coronary artery wall, which can disrupt the blood flow, leading to a heart attack without plaque buildup.
Blood Clots
Blood clots can form in any part of the body and may travel to the heart, blocking blood flow temporarily and potentially leading to a heart attack.
Severe Stress
Also known as Broken Heart Syndrome, have similar symptoms to a heart attack due to sudden muscle weakness in the heart.
Drug Use
Certain drugs, such as cocaine and more, can cause spasms or damage to arteries, resulting in heart attacks.

According to PubMed, conditions like MINOCA, SCAD, coronary artery spasms, and more can also lead to heart attacks. It is advisable to consult a healthcare professional for personalised suggestions.
