Fig. 1 Data is from the Definitive Healthcare ClaimsMx product for calendar year 2021. Claims data is sourced from multiple medical claims clearinghouses in the United States and is updated monthly. Data is accurate as of August 2022.
Cleveland Clinic Main Campus, located in Ohio, ranks at the top of our list with more than one million cardiovascular disease primary diagnoses in 2021. This facility has several hundred thousand more outpatient diagnoses for cardiovascular diseases than the remaining hospitals on our list. This may be because Ohio is one of the least heart healthy states in the U.S. Out of the 50 states, Ohio ranked sixth for the most heart disease deaths in 2020, according to mortality data tracked by the CDC. On the other hand, the Cleveland Clinic’s heart program is consistently named number one in the nation by publications like U.S. News & World Report.
Many of the hospitals on this list, like Mount Sinai Medical Center in New York and University Hospital in Michigan rank highly on our top hospitals by total operating expenses. Cleveland Clinic Main Campus and IU Health Methodist Hospital in Indiana also feature on our list of the top 20 national surgical quality improvement program (NSQIP) hospitals.
What is heart disease?
Cardiovascular disease (CVD) affects a person’s heart or blood vessels. The World Heart Federation describes four main types of CVD:
- Coronary heart disease: This occurs when the heart’s blood supply is blocked or interrupted by fatty substances in the arteries.
- Stroke: A serious medical condition that can lead to brain damage and possibly death if blood flow to the brain is restricted or stopped.
- Peripheral arterial disease: This occurs when there is a blockage in the arteries of a person’s limbs.
- Aortic disease: A type of heart valve disease affecting the aorta, the largest blood vessel in the body.
There are many symptoms of CVD that could indicate poor heart health. Some symptoms include chest discomfort, pain in the throat or jaw, swollen extremities, an irregular heartbeat, and more.
