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 […]
