Comment: The evidence summarized here makes a powerful case for melatonin as a therapeutic agent in cardiovascular health, a potent, naturally occurring neuroendocrine hormone with impressive antioxidant and anti-inflammatory properties. What stands out most is the breadth of its potential benefits: from protecting the heart muscle during a heart attack (I/R injury) to suppressing damage […]
Comment: This meta-analysis offers a compelling signal for melatonin’s role in palliative care for Heart Failure (HF). The statistically significant and moderate-certainty finding that melatonin improves Quality of Life (QoL) is highly relevant for patients struggling with chronic symptoms. The observed reduction in fatigue and improvement in sleep quality strongly supports this benefit. However, the […]
Comment: This is an important one for several reasons. Nocturnal hypertension is more closely associated with adverse cardiovascular outcomes and mortality than daytime hypertension, with nighttime systolic blood pressure being a stronger predictor of risk even after adjusting for daytime values. The reduction levels seen with controlled release melatonin may look minimal, but are actually […]
Comment: This is a classic “real-world evidence” abstract that generates a frightening headline—a 90% increased risk of heart failure!—but whose findings are likely the result of a fatal flaw: confounding by indication. It’s impossible to fully judge a study from a conference abstract alone, as the methodology is never described in sufficient detail so we’ll […]
Comment: This study is a classic example of one that is both exciting and deeply frustrating. The exciting part: A simple, cheap intervention (melatonin) was associated with a 70% relative reduction in death or heart failure readmission after a heart attack, supported by a significant, positive change in the MMP-9 biomarker. The frustrating part: The […]
Comment: I am in general not a fan of intermittent fasting as my experience is it puts the body in a state of stress, which may give short term gains, but longer term negative outcomes. This is a study showing that skipping breakfast increases metabolic syndrome, including blood sugar, blood pressure, blood lipids and central […]
Meta-analyses showed reductions in the absolute risk of 0.8% (95% CI, 0.4%-1.2%) for all-cause mortality, 1.3% (95% CI, 0.9%-1.7%) for myocardial infarction, and 0.4% (95% CI, 0.2%-0.6%) for stroke in those randomized to treatment with statins,
Comment: The traditional cardiological focus on lowering LDL-C in the elderly rests on a foundation of biochemical plausibility that is increasingly dismantled by actual survival data. This systematic review identified a critical physiological disconnect: for those over age 60, high LDL-C is not a mortality stressor but is actually associated with a longer lifespan. In […]
Comment: Another in a line of studies showing that our concept of cholesterol is wrong when it comes to the outcomes that matter. This one is particularly interesting as it breaks it down by age, showing that as we get older, higher cholesterol becomes more protective. The Wonk Debate – Audio Critique & Clinical Commentary: […]
Comment: Another in a series of studies that contradicts the dogma that lower cholesterol is better. Although the authors calculated cut off points, using the spline graphs you can see that cholesterol up to about the 230 range is lowest risk of overall deaths and even 300 is better than 160. For cancer you’re safer […]
