Yeah because people who get severe covid are immune compromised, and that means they get are at high risk for severe illness/death from any infection, not just covid. And remember that most people who "die from covid" are old and frail and more or less at end of life. Median age for covid deaths in germany is 85.
Even if I use your position that people were to die without being infected due to their health already being somewhat compromised (which isn't the case here but I will suppose it for your trollish statements) - the point is that COVID-19 has serious and significant impacts on the cardiovascular system beyond your immediate infection and more so than we previously thought.
