Which statement accurately describes isolated systolic hypertension in the elderly?

Isolated systolic hypertension in the elderly is characterized by a systolic blood pressure that is elevated while the diastolic blood pressure remains normal or low. This condition is indeed considered a significant risk factor for myocardial infarction (MI) and stroke. As individuals age, the stiffness of large arteries can increase, leading to elevated systolic pressures. Research supports this association, indicating that isolated systolic hypertension is a predictor of cardiovascular complications and overall morbidity in older adults. Therefore, managing this form of hypertension is vital in reducing the risk of acute cardiovascular events in this population.

The other options do not accurately describe isolated systolic hypertension in the elderly. While smoking is a risk factor for various cardiovascular diseases, it is not specifically related to the occurrence of isolated systolic hypertension itself. Isolated systolic hypertension affects both genders, although it may have different prevalence rates; claiming it occurs primarily in men is misleading. Lastly, describing it as not a major risk overlooks the established relationship between this condition and significant health outcomes, undermining the necessity for appropriate management and intervention in affected individuals.
