Essential hypertension (HTN) has a complex spectrum of pathophysiological determinants and current guidelines provide limited information on high-risk groups that should be targeted for its primary prevention. The objective of our research was to identify clusters of social and metabolic factors associated with prevalent HTN in men and women from a population-based survey in Romania. Of the 1477 participants in the main study, 798 with complete data were analyzed here. Using two-step cluster analysis, one high-risk cluster in women and two high and intermediate risk for prevalent HTN in men were identified. Older age, rural area, lower education, and higher burden of metabolic factors characterized clusters with higher risk, while intermediate risk in men was characterized by a more metabolically healthy phenotype in younger individuals. In logistic regression, men in Cluster 1 vs. those in Cluster 3 had an odds ratio (OR) of 9.6 (95%CI: 4.6; 20.0), p < 0.001 for prevalent HTN, while OR for Cluster 2 vs. Cluster 3 was 3.2 (95%CI: 1.4; 7.4), p = 0.005. In women, the OR for HTN was 10.2 (95%CI: 5.7; 18.5) if assigned to Cluster 2 vs. Cluster 1, p < 0.001. These results pointed out the subgroups and communities that the primary prevention of HTN should be prioritized in.

Background: Coronary artery disease (CAD) remains a significant global health concern, being one of the most important contributors to morbidity and mortality worldwide. Accurate assessment of coronary lesions is crucial for guiding appropriate interventions and optimizing patient outcomes. Patients with acute myocardial infarction represent a population which is rarely selected in studies of intracoronary hemodynamics. Fractional Flow Reserve (FFR) has emerged as a valuable physiological index for evaluating the functional significance of coronary lesions, although the data of intravascular hemodynamic evaluation in patients with acute myocardial infarction is scarce [1-3]. In recent years, advancements in intravascular imaging techniques, such as Optical Coherence Tomography (OCT), have provided detailed insights into coronary anatomy both in acute or elective settings. [4-7]. Methods: This article aims to explore the correlation between different non-culprit vessel OCT-parameters and FFR value in the patients with recent acute myocardial infarction. The study included 114 patients with acute myocardial infarction (ST elevation myocardial infarction and non ST elevation myocardial infarction)for whom primary PCI (percutaneous coronary intervention) was performed for the culprit lesion. The non-culprit vessels with intermediate coronary stenoses (157 lesions) were evaluated in a staged procedure (during the index hospitalization) with OCT, FFR and revascularization was performed accordingly. Minimal luminal area (MLA) and percent luminal area stenosis (PSA) were analyzed in relation with the FFR value. Results: There is good correlation between OCT-derived parameters and FFR values in patients with recent acute myocardial infarction. Minimal luminal area (MLA) and percent luminal stenosis area (PSA) were independent predictors of FFR< 0,80 in multivariate logistic regression analysis. A value of 2,08 mm2 for the MLA and 76,85 % for the PSA have proved to be the best cut-offs for predicting a FFR< 0,80. Conclusions: OCT parameters are valuable additional tools in current angiographic practice, including patients with acute myocardial infarction, with the ability to bring numerous direct imagistic and indirect hemodynamic information.

Coronary collateral circulation (CCC) represents a natural adaptive mechanism capable of preserving myocardial perfusion in the presence of obstructive coronary artery disease. Although invasive angiography remains the reference method for collateral visualization, it provides limited information regarding collateral functionality and downstream myocardial protection. Echocardiography, due to its widespread availability, lack of radiation, and advances in imaging techniques, has emerged as an attractive non-invasive tool for evaluating the myocardial consequences of collateral perfusion. This review summarizes current evidence regarding the role of echocardiography in assessing coronary collateral circulation. Conventional echocardiographic parameters, stress echocardiography, myocardial contrast echocardiography, speckle-tracking imaging, myocardial work analysis and three-dimensional echocardiography are reviewed in the context of collateral-dependent myocardial function. Emerging technologies including artificial intelligence and quantitative perfusion imaging are also discussed. Rather than directly visualizing collateral vessels, echocardiography provides complementary information on the myocardial consequences of collateral-dependent perfusion through assessment of regional function, myocardial mechanics, and, with contrast techniques, tissue perfusion. However, collateral-specific validation remains limited, particularly for emerging deformation and myocardial work indices, and echocardiographic findings should be interpreted alongside coronary anatomy and physiological or perfusion measurements. Future integration with invasive assessment, multimodality imaging, and molecular markers may improve characterization of collateral-dependent myocardium.
