Heart Attack Patients Are Getting Younger and More Obese.

Young people tend to feel invincible to danger, but they're not, especially when it comes to their heart health. One of the most common misconceptions about heart health is that older people are the only ones who need to worry. 

Patients who suffer from the most severe and deadly type of heart attack, STEMI, are getting younger and more obese, according to Dr. Samir Kapadia, professor of medicine and section head for interventional cardiology at Cleveland Clinic.

"On the whole, the medical community has done an outstanding job of improving treatments for heart disease, but this study shows that we have to do better on the prevention side," said Kapadia in a statement. "When people come for routine checkups, it is critical to stress the importance of reducing risk factors through weight reduction, eating a healthy diet, and being physically active." He presented his research at the American College of Cardiology's 65th Annual Scientific Session.

Cardiovascular Disease Diagnostics and Testing

Current and emerging cardiac markers signal improved testing for better patient outcomes

Cardiovascular diseases continue to be the leading cause of death in the United States, responsible for nearly 800,000 deaths annually—or about one in every three deaths. Heart disease is the leading cause of death for both men and women, claiming the lives of about 610,000 Americans each year.1Coronary artery disease is the most common type of heart disease, killing more than 370,000 people annually.

In addition, about 5.1 million people in the United States have heart failure.2About half of the people who develop heart failure die within 5 years of diagnosis. In 2009, one out of every nine deaths included heart failure as a contributing cause. Heart failure costs the nation an estimated $32 billion each year.

In light of such dire statistics, it’s no wonder that achieving speedy diagnosis of acute myocardial infarction (AMI)—heart attack—remains a significant concern in emergency departments throughout the nation. Early triage of patients to rule-in or rule-out AMI is challenging. For many years, testing for the presence of the regulatory proteins troponin I or troponin T—both released into the bloodstream when the heart muscle has been damaged—has been the gold standard for diagnosing AMI. But recent reports have indicated that the latest generation of high-sensitivity troponin tests can increase diagnostic efficiency and improve early diagnosis of myocardial infarction.

High troponin levels may account for mental stress ischemia in cardiac patients.

Some people with heart disease experience a restriction of blood flow to the heart in response to psychological stress. Usually silent (not painful), the temporary restriction in blood flow, called ischemia, is an indicator of greater mortality risk.

Cardiologists at Emory University School of Medicine have discovered that people in this group tend to have higher levels of troponin -- a protein whose presence in the blood that is a sign of recent damage to the heart muscle-- all the time, independently of whether they are experiencing stress or chest pain at that moment.

The results are scheduled for presentation by cardiology research fellow Muhammad Hammadah, MD at the American College of Cardiology meeting in Chicago on April 3, as part of the Young Investigator Awards competition. Hammadah works with Arshed Quyyumi, MD, and Viola Vaccarino, MD, PhD, and colleagues at the Emory Clinical Cardiovascular Research Institute.

"Elevated troponin levels in patients with coronary artery disease may be a sign that they are experiencing repeated ischemic events in everyday life, with either psychological or physical triggers," Hammadah says.
