Sildenafil should be avoided in valve disease with residual pulmonary hypertension, study suggests

"Valvular disease is considered the next cardiac epidemic because of its strong association with age and the rapid aging of the population worldwide," said principal investigator Dr Javier Bermejo, a cardiologist at Hospital General Universitario Gregorio MaraƱon, Madrid, Spain. "The only established treatment is repair or replacement of the valve surgically or percutaneously," he continued. "But symptoms often remain or reappear in the long-term. Residual pulmonary hypertension is the most important risk factor for death and disability after successful correction of the valvular lesion." Pulmonary hypertension refers to increased blood pressure in the pulmonary artery. In patients with long-standing valvular disease, the high pressure in the left side of the heart is transmitted backwards to the lung vessels which react by thickening. This process may not revert after valve treatment, resulting in persistent pulmonary hypertension. Sildenafil (cen...

Anti-inflammatory therapy cuts risk of lung cancer

In most clinical trials for cancer therapy, investigators test treatments in patients with advanced disease. But a recent cardiovascular secondary prevention study has given researchers a unique opportunity: to explore the effectiveness of giving a drug to patients before cancer emerges. At the European Society of Cardiology meeting, Paul M. Ridker, MD, director of the Center for Cardiovascular Disease Prevention at BWH, and colleagues presented findings from CANTOS (Canakinumab Anti-inflammatory Thrombosis Outcomes Study). In addition to their cardiovascular results, Ridker and colleagues shared that patients who received the anti-inflammatory therapy canakinumab had a marked reduction in the incidence of lung cancer and lung cancer mortality. In this high-risk population, death from cancer was reduced by half in the group of people who received the highest dosage of the drug. These findings are detailed in a paper published simultaneously in  The Lancet . "As an inflammator...

Medical treatment may prevent, alleviate mitral valve damage after a heart attack

A research team led by investigators from Massachusetts General Hospital (MGH) and collaborators has shown, for the first time, that it may be possible to nonsurgically treat or even prevent the damage to a major heart valve that often occurs after a heart attack. In their report published in the  Journal of the American College of Cardiology , the investigators -- including co-senior authors at Boston Children's Hospital and Brigham and Women's Hospital -- describe how treatment with the antihypertension drug losartan reduced mitral valve damage in an animal model of heart attack. This sort of damage typically occurs in 25 percent of heart attack patients and can lead to heart failure and an increased risk of death. "Our study supports a new concept transforming how we think about heart valves," says Robert Levine, MD, of the Heart Valve Program and the Cardiac Ultrasound Laboratory in the Corrigan Minehan Heart Center at MGH, co-senior author of the report. ...

Young adults, especially men, fall behind in high blood pressure treatment and control

oung adults, particularly men, lag behind middle-aged and older adults in awareness and treatment of high blood pressure, putting this population at an increased risk for heart attack and stroke, according to new research in the American Heart Association's journal  Hypertension . High blood pressure is a leading risk factor for heart attack and stroke and is also a significant public health burden, costing the United States about $110 billion in direct and indirect costs in 2015, according to American Heart Association estimates. American Heart Association guidelines define blood pressure as normal at less than 120/80 and high blood pressure as 140/90 or above. "While hypertension awareness, treatment and control have improved overall since the early 2000s, all three remain worse in young adults -- those aged 18-39," said senior study author Andrew Moran, M.D., M.P.H., an assistant professor at Columbia University Medical Center in New York. The study, based on ...
