Blood pressure drug linked to death risk, study says

Blood pressure drug linked to death risk, study says

Health
March 18 (UPI) -- A well-known drug used to control blood pressure and angina has been linked to out-of-hospital heart failure, a new study says. High-doses of either nifedipine or amlodipine, two forms of the drug dihydropyridine, are both associated with a high risk of out-of-hospital cardiac arrest, according to findings presented Monday at EHRA 2019. "Nifedipine and amlodipine are often used by many cardiologists and other physicians, and the choice often depends on the prescriber's preference and personal experience," Hanno Tan, a researcher at Academic Medical Center and study author, said in a news release. "Both drugs are generally considered to be equally effective and safe and neither has been associated with sudden cardiac arrest." Cardiac arrest occurs when the heart quivers ...
Lower blood pressure boosts brain function in elderly, study says

Lower blood pressure boosts brain function in elderly, study says

Health
March 18 (UPI) -- Having lower blood pressure can boost brain function in older adults, a new study says. When elderly people took medicine to keep their systolic blood pressure around 130 mm for three years, they were less likely to suffer a heart attack, stroke or other cardiovascular event, according to research presented at the American College of Cardiology's 68th Annual Scientific Session. "I think it's an important clinical finding and a very hopeful one for elderly people who have vascular disease of the brain and hypertension," said William B. White, a researcher at the University of Connecticut School of Medicine's Calhoun Cardiology Center and study principal investigators. "With the intensive 24-hour blood pressure treatment we reduced the accrual of this brain damage by 40 p...
Blood pressure drug recall expands over third possible carcinogen

Blood pressure drug recall expands over third possible carcinogen

Health
March 2 (UPI) -- Drug companies expanded a recall of Losartan lots after detecting a third potentially cancer-causing impurity in blood pressure medication. Camber Pharmaceuticals voluntarily recalled an additional 87 lots of Losartan potassium drugs used to treat high blood pressure and congestive heart failure Thursday. The detection of trace amounts of a new potential human carcinogen, known as N-Nitroso-N-methyl-4-aminobutyric acid or NMBA, prompted the recall. On Friday, Torrent Pharmaceuticals voluntarily recalled 60 lots of Losartan potassium tablets and 54 lots of Losartan potassium/hydrochlorothiazide, similarly over the detection of trace amounts of NMBA. The recalled tablets from both companies were made by Hetero Labs in India. Each company noted it has not received any repor...
Morning exercise may lower blood pressure for older, obese people

Morning exercise may lower blood pressure for older, obese people

Health
Feb. 19 (UPI) -- Just 30 minutes of walking in the morning can lower blood pressure for overweight or obese people between ages 55 and 80, a new study says. And when women add frequent breaks from sitting during the day to this morning exercise routine, they increase the health benefits, according to a study published Wednesday in Hypertension. "We conducted this study because separate lines of inquiry have determined that a bout of exercise can acutely lower blood pressure, and more recently that prolonged sitting can increase blood pressure over the space of a day," Michael Wheeler, a researcher at The Baker Heart and Diabetes Institute and a study author, told UPI. The morning walks had a particularly strong effect on lowering systolic blood pressure, the top number in the blood pressu...

Stargazers have been scanning the skies for sightings of a highly unusual lunar eclipse, which began on Sunday night.During the spectacle, known as a "super blood wolf moon", the moon appears to glow red while seeming brighter and closer to Earth than normal.The event was initially visible from North and South America, as well as parts of western Europe. In parts of the UK some clouds obscured the view.The next total lunar eclipse is expected in two years, on 26 May 2021.Skywatchers see 'super blood wolf moon'"A little bit of sunlight is refracted by the Earth's atmosphere and reaches the Moon, bending around the edges of the Earth," says Walter Freeman, an assistant teaching professor at Syracu...
