Cardiovascular decline can progress silently, so both symptoms and objective measurements should be considered together. Warning signs may include chest pressure with exertion, shortness of breath, unusual fatigue, palpitations, lightheadedness or fainting sensations, leg swelling, and nighttime breathlessness. However, the absence of symptoms does not mean the absence of risk—high blood pressure and elevated cholesterol may remain unnoticed for years. That is why regular blood pressure checks, lab tests (lipid profile, glucose/HbA1c), and when appropriate an ECG and clinical evaluation are important. If you have a strong family history, smoke, live with obesity, or are physically inactive, proactive screening becomes even more valuable. If symptoms are sudden or severe—especially chest pain or acute shortness of breath—do not delay seeking medical care. Early detection is a strategic advantage.
