Just type “heart health” into Apple’s App Store, and you’ll find a wide range of mobile apps out there. “I believe that they (apps) have helped many patients think about their heart status and cardiovascular health awareness,” says Jonn A. Osborne, MD, PhD, director of preventive cardiology at Dallas Medical Center in Texas. “I think they have promise." But, Dr. Osborne warns, these apps can’t help you unless you’re motivated enough to input data on a regular basis to keep track of your health on a long-term basis. Along with being motivated and diligent, Osborne says that it’s important to find an app that integrates a number of things related to health, including fitness, diet, and blood pressure. He says the best apps integrate “all of these variables … as well as provide easy-to-understand and carefully vetted education and advice on how to reduce one’s heart attack risk.” RELATED: New Blood Pressure Guidelines: The Numbers That Really Matter

What to Look for in a Heart Health App

The interest in heart health apps is understandable. Heart disease is the No. 1 killer in the United States, leading to one in every four deaths, annually, according to the Centers for Disease Control and Prevention. But Osborne notes that a number of apps currently on the market have not been specifically vetted by the FDA, which can lead to “overdiagnosis” and “inappropriate worry” on the part of users. “I’m confident that we will see with time that these tools will be more accurate and useful and also prove to be cost-effective in clinical care,” Osborne adds. So, what are the benefits? For Osborne, apps work best when integrated into clinical care with the advice and review of a person’s doctor. “Healthcare is a complicated endeavor and I am excited by the potential of these technologies to reduce healthcare costs, to give the patient more control, insight, and understanding into their health, and expand access to information and data that was generally only available to healthcare providers,” Osborne says. “I believe that the best results in the future will be patients using this technology, but being guided by the education, knowledge, and experience of their healthcare providers.” In short, always consult your doctor first when you have concerns about your heart health. consult your doctor first.
