The Naked Heart is a weekly series of blogs and social media publications from English cardiologist Dr Edward Leatham. His brief is to apply 50 years of ”breathing and practicing” cardiology to make his day to day job more about educating patients than simply just diagnosing and treating them. ”The only way modern medicine can cope with the ever increasing demand is by educating our patients on basic principles and then encourage every patient to become their own physician, guided by their doctors” These podcast publications are AI constructs created to broaden the audience in an attempt to explain quite complicated, yet important facts thus sharing advances in medical knowledge with more people, ideally even before they become our patients. Each podcast is designed to broadcast alongside a weekly blog article with multiple reels and posts on social media, all accessible for free and without any product advertising via https://www.scvc.co.uk/category/naked-heart/

A young and healthy heart can double its stroke volume in a heartbeat. However, this capability diminishes with an ageing heart, especially one that has been subjected to high blood pressure, heart valve issues or metabolic conditions such as poor glucose control over many years. These factors cause the left ventricle to stiffen in many people as they age, limiting their left ventricle's ability to change its stroke volume. Consequently, any change in cardiac output in older individuals, or those with a stiff heart, increasingly relies on increasing the heart rate.
If the heart rate fails to increase with physical activity, cardiac output becomes constrained. Somewhat scarily, doctors call this "Chronotropic Incompetence" or "CI" for short.
