Understanding Blood Pressure
Blood pressure readings reflect two phases of the cardiac cycle: systole (contraction) and diastole (relaxation).
These phases represent the pressure in arteries as the heart pumps blood throughout the body.

Blood Pressure Categories
Normal blood pressure is below 120/80 mmHg, while elevated blood pressure is 120-129 systolic and under 80 diastolic.
Hypertension has two stages: stage one is 130-139 systolic or 80-89 diastolic, and stage two is 140+ systolic or 90+ diastolic.

SPRINT Trial and Guidelines
The SPRINT trial showed that intensive blood pressure control (below 120 systolic) significantly reduced cardiovascular events and mortality compared to standard care (below 140 systolic).
This led to updated guidelines emphasizing aggressive blood pressure management.

In this “Ask Me Anything” (AMA) episode, Peter delves into the critical subject of blood pressure, which is one of the three primary causes of atherosclerosis, along with high apoB and smoking. He begins by unraveling the nature of high blood pressure, its prevalence, and why it often goes undiagnosed. Peter describes in detail the proper way to accurately measure blood pressure and what determines a diagnosis. Next, Peter discusses the actionable steps one can take in response to high blood pressure, shedding light on the extent to which factors like weight loss, exercise, and nutrition can make an impact. He also explores the pharmacological options available and offers valuable insights on how to approach them.
