ReviewThe Future of Cardioprotection-Pointing Toward Patients at Elevated Risk as the Target Populations.
Translation of the cardioprotective effect by pharmacological and mechanical conditioning therapies into improvement of clinical outcome for the patients has been disappointing. Confounding factors like comorbidity and comedications may explain some of the loss in translation. However, the substantial improvement of outcome in disease states involving ischemia-reperfusion injury, that is, planned cardiac surgery, elective percutaneous coronary intervention, and even primary percutaneous coronary intervention for ST-segment myocardial infarction (STEMI), is the most plausible explanation for the missed demonstration of a clinical benefit. ⋯ As an adjunctive cardioprotective treatment beyond reperfusion, remote ischemic conditioning should address target populations at risk of extensive tissue damage, including patients who experience complications, which may induce profound myocardial ischemia in relation to cardiac surgery or elective percutaneous coronary intervention. Moreover, patients with STEMI and predictable impaired clinical outcome due to delayed hospital admission, high Killip class, cardiogenic shock, and cardiac arrest remain target groups. For high-risk patients, daily remote ischemic conditioning or the corollary of blood flow-restricted exercise may be alternative cardioprotective options during postoperative and post-myocardial infarct rehabilitation.

ReviewRenin-Angiotensin System Blockade and Mortality in Patients With Hypertension and COVID-19 Infection.
To determine the effect renin-angiotensin system blockers on the outcome in patients with hypertension and concurrent COVID-19 infection, we searched PubMed, the Cochrane Library, and Google Scholar for relevant articles. Twelve studies with a total of 16,101 patients met the inclusion criteria. ⋯ There was no difference in the risk of death between the use of angiotensin converting enzyme inhibitors and angiotensin receptor blockers (risk ratio 1.09, 95% CI [0.90 -1.32]). We conclude that the use of angiotensin converting enzyme inhibitors and angiotensin receptor blockers improves mortality in patients with hypertension and concurrent COVID-19 infection, without a significant difference between ACEIs and ARBs in this population.
