REN and chronic obstructive pulmonary disease: As reviewed by Cooper et al.,75 “LONG COVID” patients show numerous cardiovascular complications such as myocarditis, microvascular angina, cardiac arrhythmias, and blood pressure abnormalities due to dysregulation of the renin–angiotensin–aldosterone System primarily by angiotensin II and that antagonists such as Telmisartan could re‐establish cardiovascular homeostasis by blocking the actions of angiotensin II on AT1 receptors.
