Relationship between vitamin D and cholesterol levels in STEMI patients undergoing primary percutaneous coronary intervention.

Background And Aims: Special interest has been raised on vitamin D association with the metabolic profile, potentially interfering with lipid parameters and lipid-lowering therapies. The aim of the present study was to assess the impact of vitamin D on the cholesterol levels among patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI.

Methods And Results: A consecutive cohort of 450 patients admitted for STEMI treated with pPCI were retrospectively identified and divided according to tertiles values of 25(OH).

Vitamin D deficiency is associated with impaired reperfusion in STEMI patients undergoing primary percutaneous coronary intervention.

Background And Aims: Vitamin D displays a broad spectrum of cardioprotective effects, preventing oxidative stress, inflammation and thrombosis and improving endothelial function. Previous studies have associated vitamin D deficiency with more extended and severe coronary artery disease (CAD) and worse outcome, and especially among patients with ST-segment elevation myocardial infarction (STEMI). However, few data have been reported on the association of vitamin D levels with the angiographic findings and epicardial reperfusion in STEMI patients undergoing primary percutaneous coronary intervention (pPCI), that was therefore the aim of the present study.

Association between vitamin D deficiency and serum Homocysteine levels and its relationship with coronary artery disease.

Homocysteine (Hcy) elevation and vitamin D deficiency have emerged as potential markers of coronary artery disease (CAD). However, even tough hypovitaminosis D has been suggested to interfere with Hcy catabolism, no study has so far addressed the interaction of vitamin D and Hcy and their impact on CAD, that was the aim of present study. A cohort of consecutive patients undergoing coronary angiography in a single center were included and analyzed within the year 2019.

Low hemoglobin predicts high-platelet reactivity and major cardiovascular ischemic events at long-term follow-up among ACS patients receiving dual antiplatelet therapy with ticagrelor.

Background: Reduced levels of hemoglobin (Hb) represent an established marker of impaired outcomes and increased cardiovascular risk in patients with coronary artery disease, challenging the management of dual antiplatelet therapy (DAPT). However, while anemia has emerged as an independent predictor of suboptimal platelet inhibition in patients receiving clopidogrel, no study has so far evaluated the impact of Hb levels on high-on treatment platelet reactivity (HRPR) with ticagrelor and their prognostic consequences, that were the aim of the present study.

Methods: Patients on DAPT with ASA + Ticagrelor (90 mg/twice a day) after percutaneous coronary revascularization for ACS were scheduled for platelet function assessment 30-90 days post-discharge.

Determinants of vitamin D activation in patients with acute coronary syndromes and its correlation with inflammatory markers.

Background And Aim: Vitamin D deficiency is a pandemic disorder affecting over 1 billion of subjects worldwide. Calcitriol (1,25(OH)2D) represents the perpetrator of the several systemic effects of vitamin D, including the anti-inflammatory, antithrombotic and anti-atherosclerotic actions, potentially preventing acute cardiovascular ischemic events. Variability in the transformation of vitamin D into 1,25(OH)2D has been suggested to modulate its cardioprotective benefits, however, the determinants of the levels of calcitriol and their impact on the cardiovascular risk have been seldom addressed and were, therefore, the aim of the present study.

Cholecalciferol levels, inflammation and leukocytes parameters: Results from a large single-centre cohort of patients.

Background: Vitamin D deficiency represents a pandemic health problem with a broad spectrum of clinical implications. Several studies have involved lower levels of vitamin D with inflammatory disorders including cardiovascular, autoimmune and infectious disease. Indeed, the pathophysiological mechanisms are still poorly ascertained.

Association of lower vitamin D levels with inflammation and leucocytes parameters in patients with and without diabetes mellitus undergoing coronary angiography.

Background: Diabetes mellitus has been associated with a chronic low-grade inflammation and a higher risk of cardiovascular and infectious disease, that could be prevented by the effects of vitamin D. We aimed at evaluating the impact of vitamin D levels on the biomarkers of acute-phase response, inflammation and glucose metabolism in a large cohort of diabetic patients with cardiovascular disease.

Materials And Methods: Consecutive patients undergoing coronary angiography were included.

Low vitamin D levels affect left ventricular wall thickness in severe aortic stenosis.

Background: Vitamin D [25(OH)D] deficiency and degenerative aortic stenosis represent emerging conditions, linked to a progressive ageing of the population and increased frailty. Previous studies have associated lower levels of 25 (OH)D to the pathogenesis of atherosclerosis and vascular calcifications. However, few studies have evaluated, so far, the impact of vitamin D deficiency in patients with aortic stenosis, which was therefore the aim of present study.

Vitamin D levels condition the outcome benefits of renin-angiotensin system inhibitors (RASI) among patients undergoing percutaneous coronary intervention.

Background: Vitamin D deficiency is estimated as the most common medical condition worldwide, with severe implications on survival and on several inflammatory, immune-mediated and thrombotic disorders, and especially for cardiovascular disease. Recent studies have suggested that vitamin D could directly regulate the Renin-Angiotensin System (RAS) activity, therefore potentially interfering with the pharmacological effects of RAS Inhibitors (RASI), an issue that has seldom been explored. Therefore, the aim of the present study was to evaluate the prognostic impact of the use of RASI according to vitamin D levels among patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI).

Prognostic impact of Vitamin D deficiency in patients with coronary artery disease undergoing percutaneous coronary intervention.

Background: Whether Vitamin D deficiency represents an independent predictor of mortality and major cardiovascular events or rather the mirror of a more advanced clinical condition with increased comorbidities is still debated. We aimed at assessing the impact of vitamin D levels on the long-term outcomes among patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention.

Methods: Consecutive patients from a single centre were included.

Gender Differences in Platelet Reactivity in Diabetic Patients Receiving Dual Antiplatelet Therapy.

Background: Increased comorbidities and a perceived high-bleeding risk often prevent the use of dual antiplatelet therapy (DAPT) in female patients. However, more aggressive antiplatelet treatment would certainly offer additional outcome benefits in coronary artery disease, especially among diabetic patients. The aim of the present study was to evaluate the gender differences in high-residual on treatment platelet reactivity (HRPR) among diabetic patients treated with DAPT.
