6. Irregular Heartbeat (Heart Palpitations)
Heart palpitations are sensations that make the heart feel like it is:
- Racing
- Fluttering
- Skipping beats
Occasional palpitations are common, but frequent or persistent irregular heartbeats may indicate arrhythmia, a condition that can increase the risk of heart attack or stroke.
7. Pain or Cramping in the Legs
Pain in the legs while walking may signal Peripheral Artery Disease (PAD), a condition caused by plaque buildup in the arteries.
PAD reduces blood flow to the limbs and is strongly linked to cardiovascular disease.
Symptoms may include:
- Leg pain while walking
- Numbness or tingling in the feet
- Cold or pale feet
Studies show that people with PAD have a significantly higher risk of heart attack and stroke.
What Science Says About Early Heart Attack Symptoms
Research suggests that heart attacks are often preceded by prodromal symptoms — early warning signs that appear before the main event.
A study published in the Journal of Clinical Nursing found that up to 70% of patients experienced warning signs weeks before their heart attack. The most commonly reported symptoms included:
- Fatigue
- Sleep disturbances
- Anxiety
- Shortness of breath
Unfortunately, many people dismiss these symptoms as stress, aging, or temporary exhaustion.
