Adverse cardiovascular (CV) events have declined in Western countries due at least in part to aggressive risk factor control, including dyslipidemia management. The American and European (Western) dyslipidemia treatment guidelines have contributed significantly to the reduction in atherosclerotic cardiovascular disease (ASCVD) incidence in the respective populations. However, their direct extrapolation to Indian patients does not seem appropriate for the reasons described below. In the US, mean low-density lipoprotein cholesterol (LDL-C) levels have markedly declined over the last 2 decades, correlating with a proportional reduction in CV events. Conversely, poor risk factor control and dyslipidemia management have led to increased CV and coronary artery disease (CAD) mortality rates in India. The population-attributable risk of dyslipidemia is about 50% for myocardial infarction, signifying its major role in CV events. In addition, the pattern of dyslipidemia in Indians differs considerably from that in Western populations, requiring unique strategies for lipid management in Indians and modified treatment targets. The Lipid Association of India (LAI) recognized the need for tailored LDL-C targets for Indians and recommended lower targets compared to Western guidelines. For individuals with established ASCVD or diabetes with additional risk factors, an LDL-C target of <50 mg/dL was recommended, with an optional target of ≤30 mg/dL for individuals at extremely high risk. There are several reasons that necessitate these lower targets. In Indian subjects, CAD develops 10 years earlier than in Western populations and is more malignant. Additionally, Indians experience higher CAD mortality despite having lower basal LDL-C levels, requiring greater LDL-C reduction to achieve a comparable CV event reduction. The Indian Council for Medical Research-India Diabetes study described a high prevalence of dyslipidemia among Indians, characterized by relatively lower LDL-C levels, higher triglyceride levels, and lower high-density lipoprotein cholesterol (HDL-C) levels compared to Western populations. About 30% of Indians have hypertriglyceridemia, aggravating ASCVD risk and complicating dyslipidemia management. The levels of atherogenic triglyceride-rich lipoproteins, including remnant lipoproteins, are increased in hypertriglyceridemia and are predictive of CV events. Hypertriglyceridemia is also associated with higher levels of small, dense LDL particles, which are more atherogenic, and higher levels of apolipoprotein B (Apo B), reflecting a higher burden of circulating atherogenic lipoprotein particles. A high prevalence of low HDL-C, which is often dysfunctional, and elevated lipoprotein(a) [Lp(a)] levels further contribute to the heightened atherogenicity and premature CAD in Indians. Considering the unique characteristics of atherogenic dyslipidemia in Indians, lower LDL-C, non-HDL-C, and Apo B goals compared to Western guidelines are required for effective control of ASCVD risk in Indians. South Asian ancestry is identified as a risk enhancer in the American lipid management guidelines, highlighting the elevated ASCVD risk of Indian and other South Asian individuals, suggesting a need for more aggressive LDL-C lowering in such individuals. Hence, the LDL-C goals recommended by the Western guidelines may be excessively high for Indians and could result in significant residual ASCVD risk attributable to inadequate LDL-C lowering. Further, the results of Mendelian randomization studies have shown that lowering LDL-C by 5-10 mg/dL reduces CV risk by 8-18%. The lower LDL-C targets proposed by LAI can yield these incremental benefits. In conclusion, Western LDL-C targets may not be suitable for Indian subjects, given the earlier presentation of ASCVD at lower LDL-C levels. They may result in greater CV events that could otherwise be prevented with lower LDL-C targets. The atherogenic dyslipidemia in Indian individuals necessitates more aggressive LDL-C and non-HDL-C lowering, as recommended by the LAI, in order to stem the epidemic of ASCVD in India., (© Journal of the Association of Physicians of India 2024.)

Objective: In 2016, the Lipid Association of India (LAI) developed a cardiovascular risk assessment algorithm and defined low-density lipoprotein cholesterol (LDL-C) goals for prevention of atherosclerotic cardiovascular disease (ASCVD) in Indians. The recent refinements in the role of various risk factors and subclinical atherosclerosis in prediction of ASCVD risk necessitated updating the risk algorithm and treatment goals., Methods: The LAI core committee held twenty-one meetings and webinars from June 2022 to July 2023 with experts across India and critically reviewed the latest evidence regarding the strategies for ASCVD risk prediction and the benefits and modalities for intensive lipid lowering. Based on the expert consensus and extensive review of published data, consensus statement IV was commissioned., Results: The young age of onset and a more aggressive nature of ASCVD in Indians necessitates emphasis on lifetime ASCVD risk instead of the conventional 10-year risk. It also demands early institution of aggressive preventive measures to protect the young population prior to development of ASCVD events. Wide availability and low cost of statins in India enable implementation of effective LDL-C-lowering therapy in individuals at high risk of ASCVD. Subjects with any evidence of subclinical atherosclerosis are likely to benefit the most from early aggressive interventions., Conclusions: This document presents the updated risk stratification and treatment algorithm and describes the rationale for each modification. The intent of these updated recommendations is to modernize management of dyslipidemia in Indian patients with the goal of reducing the epidemic of ASCVD among Indians in Asia and worldwide., Competing Interests: Declaration of competing interest Raman Puri: Boehringer Ingelheim, Novartis Manish Bansal: Sun Pharmaceuticals, USV, Dr Reddy's Labs, Cipla, Eris Lifesciences, Intas Pharmaceuticals, AstraZeneca Pharma India, Novartis Vimal Mehta: Institutional research grants from Amgen, Boehringer Ingelheim, Novo Nordisk, Eli Lilly, LIB Therapeutics, AstraZeneca, Torrent P Barton Duell: Advisory activities: Akcea/Ionis, Esperion, Regeneron, Kaneka, Novo Nordisk.

In 2021 an estimated 74 million individuals had diabetes in India, almost all type 2 diabetes. More than half of patients with diabetes are estimated to be undiagnosed and more 90% have dyslipidemia that is associated with accelerated development of atherosclerotic cardiovascular disease (ASCVD). Patients of Indian descent with diabetes have multiple features that distinguish them from patients with diabetes in Western populations. These include characteristics such as earlier age of onset, higher frequency of features of the metabolic syndrome, more prevalent risk factors for ASCVD, and more aggressive course of ASCVD complications. In light of the unique features of diabetes and diabetic dyslipidemia in individuals of Indian descent, the Lipid Association of India developed this expert consensus statement to provide guidance for management of diabetic dyslipidemia in this very high risk population. The recommendations contained herein are the outgrowth of a series of 165 webinars conducted by the Lipid Association of India across the country from May 2020 to July 2021, involving 155 experts in endocrinology and cardiology and an additional 2880 physicians., Competing Interests: Conflict of interest Raman Puri: Boehringer Ingelheim, Novartis Vimal Mehta: Institutional research grants from Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, LIB Therapeutics, Novo Nordisk, Torrent P Barton Duell: Advisory activities: Akcea/Ionis, Esperion, Novo Nordisk, Regeneron, Kaneka.

Stroke is the second most common cause of death worldwide. The rates of stroke are increasing in less affluent countries predominantly because of a high prevalence of modifiable risk factors. The Lipid Association of India (LAI) has provided a risk stratification algorithm for patients with ischaemic stroke and recommended low density lipoprotein cholesterol (LDL-C) goals for those in very high risk group and extreme risk group (category A) of <50 mg/dl (1.3 mmol/l) while the LDL-C goal for extreme risk group (category B) is ≤30 mg/dl (0.8 mmol/l). High intensity statins are the first-line lipid lowering therapy. Nonstatin therapy like ezetimibe and proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors may be added as an adjunct to statins in patients who do not achieve LDL-C goals with statins alone. In acute ischaemic stroke, high intensity statin therapy improves neurological and functional outcomes regardless of thrombolytic therapy. Although conflicting data exist regarding increased risk of intracerebral haemorrhage (ICH) with statin use, the overall benefit risk ratio favors long-term statin therapy necessitating detailed discussion with the patient. Patients who have statins withdrawn while being on prior statin therapy at the time of acute ischaemic stroke have worse functional outcomes and increased mortality. LAI recommends that statins be continued in such patients. In patients presenting with ICH, statins should not be started in the acute phase but should be continued in patients who are already taking statins. ICH patients, once stable, need risk stratification for atherosclerotic cardiovascular disease (ASCVD)., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)
