Effects of BMI on Treatment Responses Previous epidemiologic studies as well as outcomes trials in hypertension have established that lean patients have higher CV event rates than heavier patients This phenomenon has been reported with SHEP (chlorthalidone, but not the placebo group), in LIFE and in INVEST. Most or all the patients in these trials in whom this occurred were receiving thiazide therapy

Diabetes and Hypertension Best stroke protection at SBP <12 mmhg Best CV protection at <13 mmhg Best renal protection at <14 mmhg (not lower) RAS blocker-based therapy is basis of treatment, but RAS + CCB appears superior to RAS + thiazide for CV protection, particularly in non-obese patients Newer diabetes agents like GLPs and SGLT2 inhibitors can reduce BP: could the SGLT2 agents replace thiazides in combination BP therapy?
