very low blood pressure can lead to increased risk for cardio-vascular events.
Data from the Treating to New Targets (TNT) trial show that low blood pressure levels may lead to increased risk of cardiovascular events, including heart attack and stroke.
The relationship between systolic blood pressure (SBP) or diastolic blood pressure (DBP) and major cardiovascular events followed a J-curve with increased event rates above and below reference BP ranges (SBP130-140 mm Hg and DBP 70-80 mm Hg).
Study authors concluded that among a high-risk population with CAD enrolled in the TNT trial, despite substantial lowering of LDL-cholesterol, a J-curve relationship existed between both systolic and diastolic BP and the risk of future cardiovascular events, suggesting that low BP levels may be harmful.
"Our findings negate the dictum that with blood pressure, lower is always better," said study co-author Franz Messerli, M.D., director, Hypertension Program at St. Luke's-Roosevelt Hospital, New York, NY.
so even with very low BP we are still at higher risk for cardiovascular events.this is a part of article that i read in a journal few days back.
