In the context of recent climate change, global warming, industrial growth, and population expansion, air pollution has emerged as a significant environmental and human health risk. This study employed a multivariable Poisson regression analysis to examine the association between short-term exposure to atmospheric pollutants (nitrogen dioxide—NO₂, sulfur dioxide -SO₂, ozone—O₃, and particulate matter with a diameter less than 10 μm-PM₁₀) and hospital admissions for non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Daily data on NSTE-ACS admissions, air pollutants, and meteorological variables were collected from January 2019 to December 2021. Elevated NO₂ concentrations were associated with a higher risk of NSTE-ACS hospitalization, notably in spring (OR: 1.426; 95% CI: 1.196–1.701). Hypertensive individuals (OR: 1.101; 95% CI: 1.007–1.204) and those diagnosed with unstable angina (OR: 1.107; 95%CI: 1.010–1.213) exhibited heightened susceptibility to elevated NO₂ concentrations. A 10 μg/m³ increase in NO₂ during spring at lag 07 (OR: 1.013; 95% CI: 1.001–1.025) and O₃ in winter at lag 05 (OR: 1.007; 95% CI: 1.001–1.014) was correlated with an elevated daily occurrence of NSTE-ACS admissions. Short-term exposure to various air pollutants posed an increased risk of NSTE-ACS hospitalization, with heightened sensitivity observed in hypertensive patients and those with unstable angina. Addressing emerging environmental risk factors is crucial to mitigate substantial impacts on human health and the environment.

Background and Objectives: Acute coronary syndrome (ACS), a prevalent global cardiovascular disease and leading cause of mortality, is significantly correlated with meteorological factors. This study aims to analyze the impact of short-term changes in meteorological factors on the risk of ACS, both with and without ST-segment elevation, and to identify vulnerable subgroups. Materials and Methods: Daily ACS admissions and meteorological variables were collected from October 2016 to December 2021. A generalized linear model (GLM) with a Poisson distribution was employed to examine how short-term fluctuations in meteorological parameters influence ACS hospitalizations. Subgroup analyses were conducted to identify the populations most vulnerable to climate change. Results: Multiple regression analyses showed that short-term fluctuations in atmospheric pressure (≥10 mbar) and air temperature (≥5 °C) seven days prior increased the number of ACS hospitalizations by 58.7% (RR: 1.587; 95% CI: 1.501–1.679) and 55.2% (RR: 1.552; 95% CI: 1.465–1.644), respectively, notably impacting ST-segment elevation myocardial infarctions (STEMIs). The least pronounced association was observed between the daily count of ACS and the variation in relative air humidity (≥20%), resulting in an 18.4% (RR: 1.184; 95% CI: 1.091–1.286) increase in the risk of hospitalization. Subgroup analysis revealed an increased susceptibility among men and older adults to short-term variations in weather parameters. Conclusions: The findings indicate that short-term changes in weather conditions are associated with an increased risk of ACS hospitalizations, particularly STEMIs. Male and older adult patients exhibit heightened susceptibility to variations in climatic factors. Developing effective preventive strategies is imperative to alleviate the adverse consequences of these environmental risk factors.

Cardiovascular diseases (CVDs) persist as a significant contributor to global morbidity and mortality despite advances in medical technology. Air pollution has emerged as a significant contemporary challenge due to increased energy consumption and rapid economic development. The study utilized multivariable Poisson regression and Distributed Lag Models (DLM) to assess the link between brief exposure to outdoor air pollutants (PM₁₀—particulate matter with a diameter ≤ 10 μm, NO₂—nitrogen dioxide, and O₃—ozone) and the risk of acute myocardial infarction with ST-segment elevation (STEMI) hospitalization, stratified by season. The research was conducted from January 2019 to December 2021 at the University Hospital in Timisoara, Romania, and daily records were collected for STEMI admissions, atmospheric pollutant levels, and meteorological parameters. The most pronounced impacts were observed with each 10 μg/m³ increase at lag 07 for PM₁₀ during summer, leading to a 2% increase in STEMI admissions, and for NO₂ during spring at lag 07, resulting in a 0.9% rise in CVD incidence. Men, middle-aged adults, and older adults exhibited greater susceptibility to elevated NO₂ and PM₁₀ concentrations than women and younger individuals. Brief exposure to diverse air pollutants heightens the likelihood of hospitalization due to STEMI, particularly among men and adults over 45. Effective measures must be implemented to mitigate these impacts, especially for vulnerable populations.

Background and Objectives: The present study evaluates documentation and control of cardiovascular risk factors (RFs) in patients with coronary heart disease (CHD) during routine outpatient visits at a single tertiary center in western Romania and places these findings in descriptive context relative to SURF-CHD reports from Europe. Materials and Methods: We have enrolled 136 consecutive patients between 18 and 80 years old with coronary artery disease attending routine outpatient clinic check-ups between May 2019 and July 2020. All patients had been diagnosed with acute coronary syndrome or stable angina pectoris and had been treated either by PCI or CABG. Comparisons with SURF-CHD were primarily descriptive due to non-harmonized denominators and lack of patient-level data; inferential testing was limited to variables with clear n/N in both cohorts. Results: Most patients (81%) were males with a mean age of 61.7 years. 93.4% of the patients had undergone PCI, and 4.4% had coronary artery bypass graft (CABG). Regarding risk factors, 25% were current smokers, while 50% were former smokers and the mean BMI value was 29.9 (±6.07). While most patients (80.1%) revealed no previous history of dyslipidemia, 62.5% had no previous history of arterial hypertension, and 84.6% had no previous history of diabetes mellitus. Mean LDL cholesterol levels after a major coronary event remained 93.55 (±43.52) mg/dL, mean HbA1c levels were 7.86 (±1.40)%, while mean systolic blood pressure was 129 (±14.9) mmHg. Conclusions: In this single-center audit, several modifiable RFs remained suboptimally controlled despite established CHD. These results should not be generalized nationally; rather, they highlight center-level opportunities for improving secondary prevention and underscore the need for multicenter, nationally representative registries in Romania.
