Dyslipidemia and peripheral arterial disease

Indian Heart J. 2024 Jan 13:S0019-4832(24)00010-5. doi: 10.1016/j.ihj.2024.01.010. Online ahead of print.ABSTRACTPeripheral arterial disease (PAD) affects 12 % of adult population and is increasing globally and in India. Peripheral arterial disease when associated with atherosclerosis in two or more other arterial beds such as coronary artery disease (CAD), mesenteric/renal artery and cerebrovascular disease (CVD), is known as polyvascular disease. The Reduction of Atherothrombosis for Continued Health (REACH) registry reported that 1 out of 6 patients had multi-vascular bed involvement. Progression of PAD to critical limb ischaemia (CLI) is seen in 1 % of affected patients per year, but patients who progress to CLI may have a 10- to 15-fold increased risk of cardiovascular death. The 2019 ECS/EAS guidelines for the management of dyslipidaemias have suggested that for primary or secondary prevention in very high risk, patients should follow a therapeutic regimen that achieves >50 % LDL-C reduction from baseline and an LDL-C goal of <55 mg/dl. High Intensity Statin is mainstay of treatment but optimal management is inadequate. Statin treatment reduces all-cause mortality by 39 %, CV death by 41 %, CV outcomes by 34 %, ischaemic stroke by 28 %, acute limb ischaemia by 30 % and amputations by 35 %. Ezetimibe when added to statins in IMPROVE-IT trial, showed significant reduction of MACE. PCSK9 inhibitor (FOURIER TRIAL) showed reduction in primary end point in PAD vs Non PA...
