Why Recognizing These Early Signs Is Crucial Now More Than Ever
Heart attacks don’t always announce themselves dramatically. Research shows that many people experience prodromal (early) symptoms days, weeks, or even a month before the event.
Studies, including those reviewed by the American Heart Association, indicate these signs are especially common in women, where up to 70% report unusual fatigue without classic chest pain.
But men can experience them too. These signals often reflect reduced oxygen delivery due to building plaque in arteries.
The frustrating reality? Many dismiss them as indigestion, anxiety, or “just getting older.”
Here’s the truth: Listening to your body early can lead to simple tests and interventions that address issues before they escalate.
You’re already taking a positive step by reading this—keep going.
The 7 Subtle Warning Signs to Watch For
These signs can come and go, varying in intensity. They’re not always tied to exertion, and rest might not fully relieve them.
Sign #1: Unexplained Cold Sweats or Clammy Feeling
Breaking out in a sudden cold sweat, even in a warm room or without activity? This can signal your body’s stress response kicking in as the heart works harder.
The American Heart Association lists cold sweats as a possible accompanying sign during heart strain.
It happens when reduced blood flow triggers the autonomic nervous system, releasing hormones that cause sweating and pallor.
Many people mistake it for a flu bug or anxiety.
But if it’s new and recurring, it’s worth noting.
Track how often it happens and any triggers.
Sign #2: Unusual Fatigue or Extreme Tiredness
Feeling profoundly exhausted after minimal effort, like climbing stairs or even resting? This is one of the most reported early signs, especially in women.
Research published in Circulation found that up to 70% of women experienced unusual fatigue in the weeks before a heart attack.
Narrowed arteries mean less oxygen reaches muscles and organs, leading to deep weariness that caffeine or sleep doesn’t fully fix.
It’s not your typical end-of-day tiredness—it’s overwhelming and persistent.
If your energy feels drained without clear reason, pay attention.
Here’s a quick tip: Note if rest truly restores you or if the fatigue lingers.
