The First Signs Of Heart Disease Aren’t What You Think...

#longevity #drrichardson #insulinresistance Heart disease rarely begins with a dramatic event. In most cases, the underlying biological changes have been developing silently for years before somebody experiences a heart attack, heart failure, or stroke. As an A&E doctor, one of the most striking things I’ve seen over the last decade is how often patients look back and realise there were warning signs long before they ever sought medical attention. In this video, I explain what those early signs can look like in real life, the subtle changes that are often dismissed as ageing, stress, poor fitness, or simply “being tired”. Breathlessness walking upstairs. Fatigue that feels slightly out of proportion. A rising resting heart rate. Needing an extra pillow at night. None of these symptoms alone means somebody has heart disease, but together they can reflect important changes happening within the cardiovascular system years before a diagnosis is made. We’ll also look at the underlying biology driving these symptoms, including arterial stiffness, endothelial dysfunction, insulin resistance, inflammation, sleep disruption, and the gradual loss of cardiovascular reserve that develops over time. Most importantly, I want to highlight that these processes are often modifiable. Cardiovascular disease is not something that suddenly appears overnight, and there is usually a significant window where intervention can meaningfully change the trajectory.
