The association of conventionally medicated systolic and diastolic blood pressure level and mortality from cardiovascular disease: is the lower the better in high stroke population?

Hypertension has become majority morbidity and a leading factors for the cardiovascular disease mortalities in the current society [1, 2]. While hypertensive managements has improved since the twentieth century , the optimal blood pressure (BP) among hypertensive patients remains in question. The new American Heart Association/American College of Cardiology (AHA/ACC) guidelines suggest health benefit for systolic blood pressure (SBP) below 130 mmHg and diastolic blood pressure (DBP) below 80 mmHg . It remains unclear whether this is also favorable for Asian and East-European population where, in contrast to Western countries, mortality from stroke has been higher than that from coronary heart disease (CHD) . We recently examined an association of the combined category of SBP/DBP with mortality from cardiovascular disease (CVD); the results showed J-curved CVD mortality association among the participants with ongoing antihypertensive treatment but not normotensive...
