🟣 Coronary artery disease (CAD) happens when the arteries that supply blood to the heart become narrowed by plaque, so the heart gets less oxygen-rich blood.
➟ This commonly causes angina, which is chest discomfort triggered when the heart needs more oxygen, such as during walking, climbing stairs, or stress.
🟣 Common signs and symptoms
➟ Chest pressure, tightness, squeezing, heaviness, or aching
→ This is the classic symptom. Many people describe it as pressure rather than a sharp stabbing pain.
➟ Shortness of breath
→ Breathing may feel harder during activity because the heart is not getting enough blood flow.
➟ Pain spreading outward
→ Discomfort can move to the arm, shoulder, neck, jaw, back, or sometimes upper belly.
➟ Sweating, nausea, dizziness, or feeling faint
→ These can happen when reduced blood flow becomes more significant, and they deserve attention, especially if they come with chest symptoms.
➟ Unusual tiredness
→ Some people, especially women, may notice fatigue or weakness more than classic chest pain.
🟣 How symptoms often behave
➟ Worse with exertion or emotional stress
→ Stable angina usually appears during physical activity or strong emotions because the heart needs more oxygen at those times.
➟ Sometimes no symptoms at all
→ CAD can be silent and may only be found on testing, or first show up as a heart attack.
🟣 Important point
➟ Not everyone gets the same pattern
→ Women, older adults, and people with diabetes are more likely to have less typical symptoms or even symptoms without obvious chest pain.
🟣 Emergency warning signs
➟ Severe or persistent chest pain or pressure
➟ Major shortness of breath
➟ Sweating, nausea, or dizziness with chest discomfort
➟ Pain spreading to the arm, jaw, neck, or back
→ These can mean a heart attack and need urgent medical help immediately.
