Cardiovascular outcomes, heart failure, cardio-renal protection, hypertension, and lipid-lowering trials in diabetes and endocrinology.

CARDS demonstrated that atorvastatin 10 mg reduces major cardiovascular events by 37% and stroke by 48% in patients with type 2 diabetes and normal to mildly elevated LDL-cholesterol without prior CVD, confirming that cardiovascular risk rather than LDL level should determine statin initiation and establishing universal statin use in primary cardiovascular prevention for type 2 diabetes.

HPS demonstrated that simvastatin reduces major vascular events by 24% across all high-risk patients regardless of baseline LDL-cholesterol level, including those with diabetes without established coronary disease, eliminating the treatment threshold concept and establishing absolute cardiovascular risk as the primary criterion for statin therapy — one of the most influential results in preventive cardiology.

WOSCOPS demonstrated that pravastatin reduces the combined incidence of nonfatal MI and coronary death by 31% in men with hypercholesterolaemia and no prior MI, establishing the primary prevention indication for statin therapy and providing the first large randomised evidence for population-level lipid lowering in high-risk individuals without established cardiovascular disease.

The 4S trial demonstrated that simvastatin reduces all-cause mortality by 30%, coronary death by 42%, and major coronary events by 34% in patients with established coronary heart disease and no excess non-cardiovascular mortality, resolving the safety debate and establishing statin therapy as the standard of care in secondary cardiovascular prevention.

VADT demonstrated that intensive glucose control achieving a median HbA1c of 6.9% did not significantly reduce cardiovascular events or mortality in veterans with long-standing type 2 diabetes and high cardiovascular disease prevalence, completing the ACCORD/ADVANCE/VADT triptych that defined the limits of aggressive glycaemic management in advanced disease.

ADVANCE demonstrated that intensive glucose control targeting HbA1c below 6.5% using a gliclazide-based strategy reduces nephropathy by 21% and the microvascular composite by 14% in high-risk type 2 diabetes, without the mortality hazard observed in ACCORD, providing important context for how glycaemic targets and treatment strategies interact with safety outcomes.
