Researchers have projected that aggressively lowering blood pressure could help prevent more than 100,000 deaths in the US each year. Experts from across the country built upon the landmark Systolic Blood Pressure Intervention Trial which found that decreasing blood pressure to 120 mmHg compared to 140 mmHg reduced heart attack, stroke and death in people that were at high risk. Until now, the number of lives that could be saved was unknown.
