This is the most common symptom of heart disease, usually felt as pressure, tightness, or burning in any part of the chest, especially on the left side. The pain may sometimes radiate to the left arm, neck, jaw, or back.
Heart disease can cause shortness of breath, especially after physical activity or while sleeping. You may feel a lack of air and the need to take deep or open-mouth breaths.
Feeling extremely tired or experiencing a sudden decrease in physical stamina for no apparent reason could signal that the heart is not effectively pumping blood, leading to an insufficient oxygen supply in the body.
Reduced blood flow to the brain can cause dizziness, lightheadedness, or even temporary loss of consciousness.
Sudden weakness or numbness in one side of the body, especially in the face, arm, or leg, may be a sign of a stroke.
Sudden blurred vision, double vision, or loss of vision in one eye may indicate a stroke.
Difficulty speaking clearly, understanding language, or reading comprehension can also be signs of a stroke.
