Carbon Monoxide and Stroke: A Time Series Study of Ambient Air Pollution and Emergency Hospitalizations
Recent experimental and clinical studies suggested that exogenous carbon monoxide (CO) at low concentrations may have beneficial neuroprotective effects under certain circumstances. However, population-based epidemiological studies of environmentally relevant CO exposure generated mixed findings. The present study aimed to examine the short-term association of ambient CO with emergency stroke hospitalizations.

Short-term effects of air pollution on a range of cardiovascular events in England and Wales: case-crossover analysis of the MINAP database, hospital admissions and mortality
Conclusions This study found no clear evidence for pollution effects on STEMIs and stroke, which ultimately represent thrombogenic processes, though it did for pulmonary embolism. The strongest associations with air pollution were observed with selected non-MI outcomes.

Impaired Pulmonary Diffusion in Heart Failure With Preserved Ejection Fraction
Conclusions Subjects with HFpEF display altered pulmonary function and gas exchange at rest and especially during exercise, which contributes to exercise intolerance. Novel therapies that improve gas diffusion may be effective to improve exercise tolerance in patients with HFpEF.

Smoking cessation reduces the lectin-like low-density lipoprotein receptor index, an independent cardiovascular risk marker of vascular inflammation
AbstractVessel wall inflammation promotes the destabilization of atherosclerotic plaques. The lectin-like oxidized low-density lipoprotein (LDL) receptor-1 (LOX-1) expressed by vascular cells and monocytes. LOX index is calculated by multiplying LOX-1 ligand containing apolipoprotein B level with the soluble LOX-1. A high LOX index reflects an increased risk for stroke and myocardial infarction. However, the change in LOX index after smoking cessation and the relationship between smoking-related variables and LOX index are unknown. Relation of the clinical parameters to the LOX index was examined on 180 subjects (135 males...

The Association Between Ambient Air Pollution and Atrial Fibrillation
Int Heart J. 2021 Mar 6. doi: 10.1536/ihj.20-523. Online ahead of print.ABSTRACTAtrial fibrillation (AF) is the most common cardiac arrhythmia; it has been known to increase the risk of stroke and heart failure. The association between air pollutants and AF has remained to be controversial. Thus, in this study, we sought to undertake a systematic review and meta-analysis in order to assess the short- and long-term effects of ambient air pollution on AF.We searched PubMed, Web of Science, Embase, and Ovid for all related studies up to October 2019. We used the random-effects model to estimate the excess risk percentage (ER%...

Effect of Recombinant Human Brain Natriuretic Peptide on Acute Carbon Monoxide Poisoning Complicated with Heart Failure with Reduced Ejection Fraction
Int Heart J. 2022;63(2):312-318. doi: 10.1536/ihj.21-170.ABSTRACTThis paper aims to observe the effect of recombinant human brain natriuretic peptide (rhBNP) on treatment of acute carbon monoxide poisoning (ACMP) complicated with heart failure with reduced ejection fraction (HFREF).A total of 103 patients with ACMP complicated with HFREF admitted to our department from October 2016 to March 2020 were observed. Patients were divided into control group (50 cases) and experimental group (53 cases). The control group was given diuretic, vasodilator, and digitalis treatment, and the experimental group was supplemented with rhBN...
