Cancer, coronavirus are a dangerous mix, new studies find

New research shows how dangerous the coronavirus is for current and former cancer patients. Those who developed COVID-19 were much more likely to die within a month than people without cancer who got it, two studies found.

Strokes in the spine are rare—but dangerous

Weighing in at about the same as when he graduated high school, Brian Muscarella, 62, eats a healthy diet and enjoys plenty of physical activity. Indeed, he has completed the New York City Marathon four times.

Accurately measuring blood pressure at home

High blood pressure is one of the top risk factors for heart attack and stroke. It's also common among people who develop severe COVID-19 symptoms.

Hypertension

Hypertension, also referred to as high blood pressure, HTN or HPN, is a medical condition in which the blood pressure is chronically elevated. In current usage, the word "hypertension" without a qualifier normally refers to systemic, arterial hypertension.

Hypertension can be classified as either essential (primary) or secondary. Essential hypertension indicates that no specific medical cause can be found to explain a patient's condition. About 90-95% of hypertension is essential hypertension. Secondary hypertension indicates that the high blood pressure is a result of (i.e., secondary to) another condition, such as kidney disease or tumours (adrenal adenoma or pheochromocytoma).

Persistent hypertension is one of the risk factors for strokes, heart attacks, heart failure and arterial aneurysm, and is a leading cause of chronic renal failure. Even moderate elevation of arterial blood pressure leads to shortened life expectancy. At severely high pressures, defined as mean arterial pressures 50% or more above average, a person can expect to live no more than a few years unless appropriately treated. Beginning at a systolic pressure (which is peak pressure in the arteries, which occurs near the end of the cardiac cycle when the ventricles are contracting) of 115 mmHg and diastolic pressure (which is minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood) of 75 mmHg (commonly written as 115/75 mmHg), cardiovascular disease (CVD) risk doubles for each increment of 20/10 mmHg.
