As people age, structural and functional changes occur in the cardiovascular system. Arteries tend to lose their elasticity and become stiffer, making it harder for blood to flow smoothly. This can lead to elevated blood pressure, which puts extra strain on the heart. Over time, the heart’s pumping efficiency may decline, reducing the amount of oxygen and nutrients delivered to vital organs. These changes significantly increase the risk of developing conditions like heart failure, arrhythmia, or other age-related cardiovascular diseases.
