The best first-line monotherapy for hypertension remains uncertain, as current guidelines suggest that thiazides, angiotensin-converting enzyme inhibitors (ACEis), angiotensin receptor blockers (ARBs), and calcium channel blockers (CCBs) are appropriate in the absence of specific comorbidities. We aimed to compare the outcomes of first-line antihypertensive classes in a real-life setting with a long follow-up period. ⋯ When initiating pharmacotherapy for hypertension with a single drug, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and calcium channel blockers were associated with similar risk of MI, ACS, stroke, or HF when compared to thiazides, while beta-blockers were associated with increased risk.

National heart failure guidelines recommend quadruple therapy with renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists, and sodium-glucose cotransporter 2 inhibitors for patients with heart failure with reduced ejection fraction (HFrEF), most of whom also receive loop diuretics. However, the guidelines are less clear about the safe approaches to discontinuing older drugs whose decreasing or residual benefit is less well understood. The objective of this study was to examine whether digoxin can be safely discontinued in patients with HFrEF receiving beta-blockers. ⋯ Digoxin can be discontinued without increasing the risk of adverse outcomes in patients with HFrEF receiving beta-blockers. Future studies need to examine the residual benefit of older heart failure drugs to ensure their safe discontinuation in patients with HFrEF receiving newer guideline-directed medical therapy.

Post-acute COVID-19 syndrome (PACS) has been linked to microvascular endothelial dysfunction as a potential underlying pathomechanism and can manifest even following a mild course of the initial infection. Prevalence of microvascular endothelial dysfunction and circulating natriuretic peptides in such PACS patients remains unknown. ⋯ Peripheral microvascular endothelial dysfunction was prevalent in a symptomatic PACS population long after recovery from a mild acute infection. Increases in NT-proBNP levels were associated with microvascular endothelial dysfunction, suggesting a link between, and providing a foundation for, future studies on post viral microvascular endothelial dysfunction in PACS.

Characteristics of Vaccine Safety Observational Studies and Authors' Attitudes: A Systematic Review.
Postlicensure observational studies are the mainstay of vaccine safety evaluation. However, these studies have well-known methodological limitations, rendering them particularly vulnerable to unmeasured confounding. We sought to describe high-impact observational studies of vaccine safety, investigate the authors' attitudes toward their study's findings and limitations, and report on spin practices. ⋯ Although our findings are somewhat limited by subjectivity in study assessments, they suggest that editors and reviewers of high-impact journals should ensure that the language used in reporting observational studies accurately reflects the findings and their limitations.
