Intro

In this episode, Dr. Paul Ridker, a pioneer in the field of cardiovascular inflammation, joins the CardioNerds (Dr. Gurleen Kaur, Dr. Richard Ferraro, and Dr. Nidhi Patel) to discuss the evolving landscape of inflammation as a key factor in cardiovascular risk reduction. The discussion dives into the importance of biomarkers like high-sensitivity C-reactive protein (hs-CRP) in guiding treatment strategies, the insights gleaned from landmark trials like the JUPITER and CANTOS studies, and the future of targeted anti-inflammatory therapies in cardiology. Show notes were drafted by Dr. Nidhi Patel.

Pearls - Targeting Inflammation for Cardiovascular Risk "If you don’t measure it, you can’t treat it”: Incorporate hs-CRP into routine practice for patients at risk of cardiovascular events, as it provides crucial information for risk stratification and management. Recognize the dual benefits of statins in lowering both LDL and inflammation, particularly in patients with elevated hs-CRP. Encourage patients to adopt heart-healthy habits, as lifestyle changes remain foundational in reducing both cholesterol and inflammatory risk. Reminder that most autoimmune or inflammatory diseases, from psoriasis to Addison’s disease to lupus to scleroderma to inflammatory bowel disease, have been shown to have elevated cardiovascular risk Ongoing randomized trials including ZEUS, HERMES, and ARTEMIS will inform whether novel targeting of IL-6 can safely lower cardiovascular event rates or slow renal progression Show notes - Targeting Inflammation for Cardiovascular Risk Why is it important to measure both LDL and hs-CRP, and what factors increase hs-CRP? Inflammation and hyperlipidemia are synergistic in promoting atherosclerosis. They interact to exacerbate plaque formation and instability, increasing the risk of cardiovascular events. Just like we measure blood pressure and LDL to know what to treat, we should measure hs-CRP to guide targeted therapy. Clinical Example: in Ms. Flame's case, despite achieving target LDL levels with statins, her elevated hs-CRP indicates ongoing inflammation and residual cardiovascular risk that should be assessed. Residual inflammatory risk should be assessed in both primary and secondary prevention. Increased BMI1, smoking2, a sedentary lifestyle3, and genetics4 (such as a higher risk of metabolic disease in South Asians) all raise hs-CRP levels. SGLTi5 and GLP-1 agonists6 have also been shown to decrease hs-CRP levels. What data do we have to support measuring hs-CRP?  Women’s Health Study7: an early study showing that hs-CRP predicted risk at least as well as LDL cholesterol and that models incorporating hs-CRP in addition to lipids were significantly better at predicting risk than models based on lipids alone. JUPITER Trial8 (Primary Prevention): Among patients with normal LDL but elevated hs-CRP there was a 44% reduction in major cardiovascular events (>50% in MI and stroke) and a 20% reduction in all-cause mortality in patients treated with statins. These results led to changes in guidelines in recognizing the need to measure and treat inflammation. CANTOS Trial9 (Secondary Prevention): Randomized >10K patients with previous MI and hs-CRP ≥ 2mg/L and found that canakinumab reduced hs-CRP level from baseline in a dose-dependent manner, without reduction in the LDL, ApoB, TG, or blood pressure.
