Almost half of US adults suffer from cardiovascular disease



And after decades of decline, the number of deaths from cardiovascular disease is rising again. In 2016, 840,678 deaths were registered compared with 836,546 in 2015, according to the association's annual report Heart and Stroke Statistics, which was published on Thursday in the medical journal Circulation

"causing cardiovascular disease in the United States and Canada enormous health and economic burdens worldwide ", write the authors.

The 48% prevalence of cardiovascular disease – nearly 121.5 million adults – is cited as a significant upward trend last year, though this was driven above all by the definition of high blood pressure. The hypertension guidelines have been updated so that people with a blood pressure of 1

30/80 or higher are now considered "hypertensive". previously the definition was 140/90.

Without high blood pressure, the overall prevalence of adult cardiovascular disease in the US is 9%, a decrease of 11.5% in 2015.

Dr. David Zhao, chief physician of cardiology and managing director of the Wake Forest Baptist Health Heart and Vascular Center in Winston-Salem, North Carolina, described the new report as a "painful reminder" that heart disease is still the leading cause of death and disease in the nation.

"Overall, we have made great progress," said Zhao, who was not involved in the report. Nonetheless, "we have not yet made any significant progress on obesity, diabetes and unhealthy behaviors", which include smoking, non-exercise, poor diet and obesity. About 8 out of 10 cardiovascular disease cases can be prevented by controlling high blood pressure, diabetes and high cholesterol, as well as maintaining a healthy lifestyle according to cardiac association.

The scorecard also shows some notable gains. Reported inactivity in adults has been declining since 1998, with the trend increasing in recent years. Passivity dropped from 40.1% to 26.9% between 2007 and 2016, according to the report.

Over the past five decades, smoking rates have also fallen: About 51% of men and 34% of women smoked in 1965, compared with only 16.7% of men and 13.6% of women in 2015.

The new report includes a new recommendation that adults should receive at least seven hours of sleep per night, to optimally promote health. A recent study found that too much or too little – more than eight hours or less than seven hours a night – was associated with a higher risk of death for all reasons.

"We really need to work hard to reduce all the risk factors to reduce the rate of cardiovascular disease," Zhao said, stressing obesity. Nearly 4 in 10 US adults and almost 1 in 5 adolescents are obese, while 7.7% of adults and 5.6% of adolescents are severely affected, according to the report.

Moreover, not all groups have made the same progress in stopping or smoking cigarettes.

"Significantly higher Prevalence rates for tobacco use are observed in Indians / Alaskan Indians and lesbian, gay, bisexual and transgender populations, as well as in those with low socioeconomic status, those with mental illness, those with HIV infection, and those who receive medical care working in the military, "the report said. "Over the last 6 years, the consumption of e-cigarettes among adolescents has increased dramatically."

Overall, Zhao believes that "there is still a lot of work to do".

We may see a downtrend In some risk factors and cardiovascular disease itself "we are not there yet," he said. "This is something we all need to think about: what can we do together to really improve our health, healthy behavior and weight?"
