Scientists Say Bottom Number in Blood Pressure Reading Also Reveals Cardiovascular Risk

Scientists Say Bottom Number in Blood Pressure Reading Also Reveals Cardiovascular Risk

Blood pressure reading, say 130/80 mmHg, includes two numbers, i.e., top number (diastolic pressure), and bottom (systolic pressure). Many times health experts have the practice to note the top number as a part of a clinical setting. Hereafter, they will have to record both numbers. New research has confirmed the fact that both numbers are essential to identify whether a patient is at heart disease risk. Scientists from Kaiser Permanente, California had conducted the trial published on Wednesday, in the New England Journal of Medicine. The research runs in contrast to long-existed the fact that higher value in the top number is more probable than the bottom number to lead in unfavorable outcomes.

Dr. Alexander Flint, leading author of the study, said this study carries a massive quantity of data to hold on a fundamental question. He added it gives a clear and obvious answer. Dr. Flint noted in every manner of data classification, both top and bottom BP readings play a significant role. As per the author, the current backward-looking analysis is the most extensive study ever. It includes analysis of more than 30 million of pressure readings, recorded between the period 2007 to 2016. About 1.3 million adults participated in the study conducted in Northern California. The trial reveals two facts. Firstly, high systolic BP shows a stronger risk factor for heart failure. Secondly, risk of heart stroke and attack also soared in pair with diastolic pressure. So people were at risk even if they have a regular systolic reading along with a higher diastolic pressure.

Systolic pressure refers to the upper number in BP reading. The figure reveals the pressure at which the heart pumps blood into arteries. Whereas, diastolic pressure is the lower number, which shows the intensity on the arteries when the heart rests or not pumping blood. Before this, many studies have revealed that high systolic BP reading is more potential to result in adverse outcomes. Thus the top number is a priority for cardiologists and experts. Dr. Flint says some experts even argue the importance of diastolic number; they call it less critical. In the end, both numbers included in the blood pressure estimation are essential.
