1. Chest Pressure or Discomfort
Chest discomfort is one of the best-known potential signs of reduced blood flow to the heart.
Some people describe it as pressure, squeezing, heaviness, fullness, or tightness rather than sharp pain.
It may appear during exercise or emotional stress and improve with rest.
This pattern can occur with angina, which happens when the heart muscle doesn’t receive enough oxygen-rich blood.
Importantly, not all chest discomfort is caused by blocked arteries. Acid reflux, muscle strain, anxiety, respiratory conditions, and other problems can produce similar sensations.
But unexplained chest pressure should never simply be dismissed.
If chest discomfort is severe, persistent, or accompanied by shortness of breath, sweating, nausea, fainting, or pain spreading to the arm, back, neck, or jaw, seek emergency medical care.
2. Shortness of Breath
Feeling unusually breathless during ordinary activity can sometimes indicate a cardiovascular problem.
If narrowed coronary arteries reduce the heart’s ability to receive adequate oxygen, physical exertion may become more difficult.
Someone who once walked comfortably up a hill might suddenly find themselves stopping to catch their breath.
Shortness of breath can also occur because of lung disease, anemia, infection, poor fitness, medication effects, and numerous other conditions.
The important issue is a change from your normal baseline.
New or unexplained breathlessness deserves medical attention, especially when it occurs alongside chest discomfort, dizziness, or unusual fatigue.
