Implication

Elevated BP components link to distinct systolic time interval changes; leaves open prognostic value or clinical utility in older adults.

Structured PICO

Population

315 male subjects aged 20-89 years, including 218 healthy normotensive subjects and 67 subjects with coronary heart disease functional class 1.

Outcome

Systolic time intervals (STI), including electromechanical systole (QS2), left ventricular ejection time (LVET), pre-ejection period (PEP), and their heart rate-corrected indices (QS2I, LVETI, and PEPI)surrogate

Elevated systolic and diastolic blood pressures are associated with distinct prolongations in systolic time intervals, independent of physical activity or mild coronary heart disease.
