Anecdotally, my cardiac surgeon neighbour told me that he is on red alert due to the risk of covid on cardiac patients, and also their expectation of patients needing urgent hospitalisation post covid recovery due to cardiac incidents, at a time when ICU beds may be in short supply.
What is the percentage of 81 year olds who have hypertension? Has got to be pretty high.

Yep, that's something that's always worth keeping in mind. Like a statistic I saw on reddit the other day which said 76% of the deaths (I think, might have been of all people on ventilators regardless of the outcome) in Italy have hypertension. Now it seems reasonable to assume that this means hypertension is a problem when you get Covid-19, but at the same time, if you were to sample a population of the same age distribution randomly, the percentage of people with hypertension would be lower, but not that much lower. So another case where it's difficult to immediately tell whether there's causation or just correlation, purely based on the numbers.
