A silent heart attack, medically known as a silent myocardial infarction (SMI), occurs without the typical and intense symptoms associated with a traditional heart attack. Most people donтАЩt even realize theyтАЩve had one. ThatтАЩs what makes it especially dangerous тАФ it goes unnoticed and untreated.
Understanding Silent Heart Attacks: Causes, Symptoms, and Prevention
While a silent heart attack may not present classic signs like chest pain or shortness of breath, it causes damage to the heart muscle and can increase your risk of future heart attacks or even sudden cardiac death.
тЪая╕П Why Are Silent Heart Attacks So Dangerous?
They Go Undetected тАУ Without symptoms, most people donтАЩt seek treatment.
Risk of Future Events Increases тАУ Your chances of a second, more severe heart attack go up.
Delayed Diagnosis тАУ Damage accumulates silently until it becomes severe.
They Happen During Sleep тАУ Many SMIs occur at night and are never even noticed.
ЁЯФН Common but Overlooked Symptoms
Even though theyтАЩre called тАЬsilent,тАЭ there are subtle signs you can watch for:
Mild discomfort in the chest or upper back
Indigestion or acid reflux that doesnтАЩt go away

Cold sweats or lightheadedness
Shortness of breath on exertion
Sleep disturbances or restlessness

Routine ECG or EKG
