Of the total study population, 538,434 (83%) were defined as vaccinated and 112,693 (17%) as unvaccinated. </p> <div class="advert ad-in-content ad-mobile auh-250"><div id="adn-00000000001fc2ca-i1p0" style="display: none"></div></div> <p>The researchers performed 1:1 matching of vaccinated and unvaccinated patients according to age, sex, other health conditions (e.g. high blood pressure, diabetes, high cholesterol, etc.), income, and region of residence. This resulted in 73,559 vaccinated patients and 73,559 unvaccinated patients for the comparative analyses.</p> <p>In addition to lower mortality rates, vaccination was associated with significantly lower risks of stroke, heart attack, myocarditis/pericarditis, and venous thromboembolism compared to people who were not vaccinated.</p> <p>Chun says this is believed to be the first analysis of COVID-19 vaccine effectiveness in a large population of heart failure patients, and the first to show a clear benefit from vaccination for that cohort.</p> <p>“The study provides strong evidence to support vaccination in patients with heart failure. However, this evidence may not be applicable to all patients with heart failure, and the risks of vaccination should be considered in patients with unstable conditions,” Chun says.</p> <div style><a href="https://link.cosmosmagazine.com/JP4n"><p align="center"><img decoding="async" class="aligncenter size-full wp-image-198773" src="data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHZpZXdCb3g9IjAgMCA3MjggMTUwIiB3aWR0aD0iNzI4IiBoZWlnaHQ9IjE1MCIgZGF0YS11PSIlMkZ3cC1jb250ZW50JTJGdXBsb2FkcyUyRjIwMjMlMkYxMSUyRkNvc21vcy1DYXRjaC1VcC1lbWJlZF83Mjh4MTUwLTEuanBnIiBkYXRhLXc9IjcyOCIgZGF0YS1oPSIxNTAiIGRhdGEtYmlwPSIiPjwvc3ZnPg==" data-spai="1" alt="Sign up to our weekly newsletter" width="600" height="154" title="longevity for heart failure patients improves with covid jabs 2"><noscript data-spai="1"><img decoding="async" class="aligncenter size-full wp-image-198773" src="https://cdn.shortpixel.ai/spai/q_lossy+ret_img+to_auto/cosmosmagazine.com/wp-content/uploads/2023/11/Cosmos-Catch-Up-embed_728x150-1.jpg" data-spai-egr="1" alt="Sign up to our weekly newsletter" width="600" height="154" title="longevity for heart failure patients improves with covid jabs 2"></noscript></p></a></div> <!-- Start of tracking content syndication.
