Scientists are testing an entirely new way to fight heart disease: whether gene editing might offer a one-time fix for high cholesterol.

New research suggests testosterone replacement therapy is safe for men with “low T” and who have cardiovascular disease or are at high risk for it.

For years, there have been claims that red wine can be good for your heart, but the World Heart Federation argues otherwise.

Results from a Cleveland Clinic trial show just how effective a new medication is for individuals who have a statin intolerance.

In a major study, a new kind of cholesterol-lowering drug helped people who can’t take the first choice, pills called statins.

In the U.S., 12 percent of people 20 years or older have high cholesterol.

For years, there have been claims that red wine can be good for your heart, but the World Heart Federation argues otherwise.

A new Cleveland Clinic study shows bariatric surgery can be an effective treatment for advanced fatty liver disease.

The U.S. Preventive Services Task Force is changing its recommendations when it comes to aspirin use to prevent heart disease and stroke. The panel now says that people over the age of 40, who don’t already have a history of heart disease, should not take the medication.

If you’re taking prescription supplements to improve your heart health, new research suggests there’s one popular pill that can come off your list. Fish oil products, containing the “good fats” from fish, have long been thought to improve heart health. Despite earlier FDA approval, scientists at the Cleveland Clinic say new research examined the benefits of prescription-strength fish oil pills. “This is a drug that is like the fish oil people buy over-the-counter, but much, much more effective. Nissen said the results of the STRENGTH trial have implications for over-the-counter fish oil products since many people take large doses to avoid the expense of prescription fish oil.

An international clinical trial finds prescription-strength fish oil may not help your heart. “A very high-dose, of a very powerful fish oil, a very effective fish oil, didn’t produce any reduction in the risk of heart attack, stroke or death,” said Nissen. Participants were given either a high-dose prescription fish oil, or a corn oil placebo. Ultimately, researchers found no significant reduction in heart attack, stroke or death for the people taking high-dose fish oil. Those in the fish oil group were also 69% more likely to develop an irregular heartbeat.

WASHINGTON U.S. regulators on Monday revoked emergency authorization for malaria drugs promoted by President Donald Trump for treating COVID-19 amid growing evidence they dont work and could cause serious side effects. The Food and Drug Administration said the drugs hydroxychloroquine and chloroquine are unlikely to be effective in treating the coronavirus. The move means that shipments of the drugs obtained by the federal government will no longer be distributed to state and local health authorities for use against the coronavirus. The actions by FDA and NIH send a clear signal to health professionals against prescribing the drugs for coronavirus. No large, rigorous studies have found the drugs safe or effective for preventing or treating COVID-19.

But according to one recent study, frequent energy drink consumption can be setting our hearts up for problems. The study compared people who drank a 32-ounce energy drink and people who did not drink energy drinks. Researchers performed electrocardiograms on the participants and discovered those who drank the energy drinks had elevated blood pressure and other changes which could lead to heart rhythm disturbances. Dr. Steven Nissen, of Cleveland Clinic, did not take part in the study but said when it comes to energy drinks, we're rolling the dice with our health. "These energy drinks -- one of the biggest problems -- is that we haven't the faintest idea what's in them," he said.

The U.S. Preventive Services Task Force is recommending that many people between the ages of 50 and 59 take aspirin to prevent heart disease and colon cancer. “It’s important to understand that there are risks for aspirin,” said Dr. Steven Nissen, a cardiologist at Cleveland Clinic. Patients should stop taking aspirin if they're taking it without a doctor’s guidance to prevent cardiovascular problems and have no history of heart disease or heart attack. “For most people who have not developed heart disease, taking an aspirin to prevent heart disease is not the right thing to do,” Nissen said. For individual patients, a doctor will be able to calculate risks and benefits from taking aspirin.
