They assessed whether the degree of LDL-C lowering correlated with reductions in cardiovascular events or death.<\/li>\n\n\n\n<li>Findings: The review concluded that there was no consistent association between the extent of LDL-C reduction and a decrease in cardiovascular events or all-cause mortality. Specifically, they argued that statins\u2019 benefits might not be primarily due to LDL-C lowering but could relate to other effects (e.g., anti-inflammatory properties). This challenges the conventional view that LDL-C reduction is the primary mechanism by which statins prevent heart disease.<\/li>\n\n\n\n<li>Implications: The authors suggested that the benefits of statins may have been overestimated, particularly for primary prevention (in people without existing heart disease), and called for a re-evaluation of cholesterol-focused guidelines.<\/li>\n<\/ul>\n\n\n\n<p>Context and Controversy<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Dr. Malhotra has been vocal about these findings, often framing them as evidence of a &#8220;cholesterol con&#8221; perpetuated by pharmaceutical interests. He argues that lifestyle interventions (e.g., diet and exercise) are more effective and safer than statins for most people.<\/li>\n\n\n\n<li>This review has been controversial. Critics, including mainstream cardiology experts, argue that it contradicts large-scale evidence from trials like those analyzed by the Cholesterol Treatment Trialists\u2019 (CTT) Collaboration, which show statins reduce major vascular events by about 25% per 1 mmol\/L reduction in LDL-C. Critics also point out potential biases in the selection of trials and the interpretation of data in Malhotra\u2019s review.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Details of the 2020 Systematic Review Context and Controversy<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-1116","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/americanheartsociety.org\/index.php?rest_route=\/wp\/v2\/pages\/1116","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/americanheartsociety.org\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/americanheartsociety.org\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/americanheartsociety.org\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/americanheartsociety.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1116"}],"version-history":[{"count":1,"href":"https:\/\/americanheartsociety.org\/index.php?rest_route=\/wp\/v2\/pages\/1116\/revisions"}],"predecessor-version":[{"id":1117,"href":"https:\/\/americanheartsociety.org\/index.php?rest_route=\/wp\/v2\/pages\/1116\/revisions\/1117"}],"wp:attachment":[{"href":"https:\/\/americanheartsociety.org\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1116"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
