Merck’s Playing with Heart Program Teams Up With Professional Baseball Clubs and Baseball Legends to Help Raise Awareness About LDL-C, Called “Bad” Cholesterol, and How It May Impact the Risk of Heart Attack or Stroke

The Yankees, Red Sox, Phillies, Braves, Astros, Cardinals, Giants, Padres, and Angels are joining Merck to help educate fans about high bad cholesterol and how it may increase the risk of heart attack or stroke

RAHWAY, N.J.--(BUSINESS WIRE)-- Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced a collaboration with nine professional baseball teams and former professional baseball players to launch the Playing with Heart educational program to help educate adults about the importance of knowing their low-density lipoprotein cholesterol (LDL-C), called “bad” cholesterol, number and the potential increased risk of heart attack or stroke.

Playing with Heart connects Merck’s commitment to cardiovascular health with baseball, America’s favorite pastime, to raise awareness and encourage adults to talk with their doctor about how lowering bad cholesterol could help lower their risk of heart attack or stroke. Visit playingwithheart.com to learn more.

Every year it is estimated that more than 800,000 people in the U.S. have a heart attack. Plaque buildup in the arteries is a major cause of heart attacks. Over time bad cholesterol can combine with fats and other substances in the blood to create plaque. Plaque buildup can lead to blockages, ruptures, and blood clots, which may increase your risk of heart attack or stroke.

“Merck is proud to join with some of the biggest franchises in baseball and with WomenHeart for this first-of-its-kind collaboration,” said Cris Regent, associate vice president, U.S. Pharma Cardiovascular and Metabolic, Merck. “Cardiovascular disease is the leading cause of death in the U.S., and through Playing with Heart, we hope to increase conversations between adults and their doctors about high bad cholesterol and the risk of heart attack or stroke.”

During the 2026 baseball season, the Playing with Heart program will feature a lineup of baseball legends, clubs, and ambassadors who will share their personal stories about high bad cholesterol. Merck, along with WomenHeart patient education network, and nine professional baseball teams, will also host in-stadium events to provide education about bad cholesterol and to help encourage adults to learn more about the increased risk of heart attack or stroke. Baseball legends, clubs, and ambassadors participating in Playing with Heart include:

• Albert Pujols, Playing with Heart National Ambassador
• The New York Yankees, and Aaron Boone, CC Sabathia
• The Boston Red Sox, and Lou Merloni
• The Philadelphia Phillies, and Charlie Manuel
• The Atlanta Braves, and Javy Lopez
• The Houston Astros, and Geoff Blum
• The St. Louis Cardinals, and Sierra Kile (daughter of the late Darryl Kile)
• The San Francisco Giants, and Dusty Baker
• The San Diego Padres, and Mark Loretta, Jake Peavy
• The Los Angeles Angels, and Bobby Valentine, Clyde Wright

“The Playing with Heart program has the potential to increase understanding of bad cholesterol and its importance to heart health,” said Celina Gorre, chief executive officer, WomenHeart. “Education is at the heart of everything we do, and the Playing with Heart program gives us an opportunity to use the visibility of baseball to help raise awareness about bad cholesterol and the risk of heart attack or stroke.”

WomenHeart, which has a network of more than 1,000 patient champions, will help bring the Playing with Heart educational program to local communities.

About atherosclerotic cardiovascular disease and risk of heart attack and stroke

Atherosclerotic cardiovascular disease (ASCVD) is a condition caused by the buildup of plaque (bad cholesterol, fats, and other substances) within the arteries, leading to narrowed or blocked blood vessels that can result in serious cardiovascular events. ASCVD includes conditions such as coronary artery disease, peripheral artery disease, and cerebrovascular disease. It is a leading cause of death in the United States, accounting for approximately 25% of all deaths in the U.S. ASCVD continues to pose a significant public health burden, underscoring the need for awareness and education.
