RESUMO

Epidemiological data on serum vitamin D levels in the population of Polish patients with angiographically confirmed coronary artery disease are limited. AIM: The aim of the study was to prospectively assess the concentrations of vitamin D in a group of patients from the Cardiological Department in Bielanski Hospital in Warsaw referred for coronary angiography due to suspected coronary artery disease. MATERIALS AND METHODS: The study included a total of 1,043 qualified patients (374 women and 669 men, age: 66,9±11,0 years) who underwent coronary angiography between the years of 2013 and 2017. Plasma 25(OH)D concentrations were assessed by electrochemiluminescence. RESULTS: The median 25(OH)D concentration in the study group was 15.2 ng/ml (range: 4.0 - 55.0 ng/ml). Optimal 25(OH)D concentrations (ie., equal to or greater than 30 ng/ml) were found in 64 patients (6%). Severe deficiencies (less than 10 ng/ml) were found in 229 patients (22%). Moderate deficiencies (concentration equal to or greater than 10 ng/ml and less than 20 ng/ml) and mild deficiencies (concentration equal to or greater than 20 ng/ml and less than 30 ng/ml) were observed in 525 (50%) and 225 patients (22%), respectively. CONCLUSIONS: Vitamin D deficiency was found in 94% of residents of central Poland with angiographically confirmed coronary artery disease. 22% of patients had a severe vitamin D deficiency. Due to the documented effects of vitamin D on the cardiovascular system and the fact that cardiovascular disease (including coronary artery disease) is still the most common cause of death in developed countries, prophylactic and therapeutic strategies should be considered to combat 25(OH)D deficiency in this group of Polish patients.

RESUMO

Introduction: Ischaemic heart disease is the main cause of death in developed countries. There are many modifiable risk factors associated with coronary heart disease (CAD). A growing number of studies point to vitamin D deficiency as a risk factor for heart attacks and the conditions associated with cardiovascular disease. This study aimed to analyse the relationship between the level of 25-hydroxyvitamin D (25(OH)D) and the severity of coronary artery atherosclerosis and to study 25(OH)D levels in non-diabetic patients hospitalised due to acute coronary syndrome and those diagnosed with stable CAD. Material and methods: oronary angiography was performed prospectively in 410 successive cardiac patients. The severity of coronary artery atherosclerosis was assessed according to the Coronary Artery Surgery Study Score (CASSS). The plasma 25(OH)D level was assessed with the electrochemiluminescence method. Results: The 25(OH)D level proved to be one of the significant determinants of the CASSS (p < 0.05). In subjects without significant lesions in the coronary arteries the 25(OH)D level was significantly higher compared to patients with one- to three-vessel coronary atherosclerosis (p < 0.05). A significantly higher 25(OH)D level was noted in patients diagnosed with stable CAD compared to patients hospitalised due to acute coronary syndrome (p < 0.01). Conclusions: Patients with one- to three-vessel atherosclerosis have a significantly lower 25(OH)D level compared to patients without significant lesions in the coronary arteries. A lower 25(OH)D level was observed in patients hospitalised due to acute coronary syndrome compared to patients diagnosed with stable CAD.

RESUMO

Several modifiable factors may influence cardiac function in diabetic patients. The aim of the study was to evaluate the influence of vitamin D level on the stage of coronary atherosclerosis in cardiac patients diagnosed with type 2 diabetes. The study was performed in 337 consecutive patients undergoing coronarography. The stage of atherosclerosis was evaluated using Coronary Artery Surgery Study Score. The plasma 25(OH)D concentration was determined by an electrochemiluminescence method. Patients without significant lesions in coronary arteries presented the highest 25(OH)D level, significantly higher than patients with one-, two-, and three-vessel coronary artery disease (CAD) (p < 0.01). Significantly lower level of the 25(OH)D was observed in patients hospitalized due to acute coronary syndrome (ACS) in comparison to patients hospitalized due to stable CAD (p < 0.001). Lower 25(OH)D levels were observed in patients with the history of myocardial infarction (MI) in comparison to patients without previous MI (p < 0.001). In cardiac patients with diabetes, the higher number of stenotic coronary arteries is associated with lower values of the 25(OH)D. A group of male cardiac patients with diabetes with significant stenosis in three coronary arteries, hospitalized due to acute coronary syndrome, with a history of previous MI and hyperlipidemia presented the lowest vitamin D level.

RESUMO

INTRODUCTION: A deficiency of 25-hydroxyvitamin D (25(OH)D) (the standard biomarker for vitamin D status) can have multiple impacts on the cardiovascular system. The aim of the study was to assess of the influence of 25(OH)D on severity of coronary atherosclerosis and lipid profile. MATERIAL AND METHODS: The study involved prospectively 637 patients subject to coronary catheterization. The stage of coronary atherosclerosis was assessed using the Coronary Artery Surgery Study score (CASSS). Plasma concentration of 25(OH)D was measured using an electrochemiluminescent immunoassay. The levels of total cholesterol (TC), high-density cholesterol (HDL-C) and triglycerides (TG) were measured using the enzymatic method, and the concentration of low-density cholesterol (LDL-C) was calculated with the Friedewald equation. RESULTS: The average level of 25(OH)D was 15.85 ng/ml. A higher level of 25(OH)D was observed in men (16.28 ng/ml vs. 15.1 ng/ml; p = 0.027). The study did not reveal any significant correlation between the level of 25(OH)D and severity of coronary atherosclerosis. It was observed however that the increase of 25(OH)D level results in an increased number of patients without significant lesions in the coronary arteries. In the whole group of women and men in the age group of 70-80 years an inverse relationship was observed between the level of 25(OH) and the severity of coronary atherosclerosis. The whole study group showed a statistically significant inverse correlation of the 25(OH)D level with TC (p = 0.0057), LDL-C (p = 0.00037) and TG (p = 0.00017). CONCLUSIONS: Women and men over 70 years showed an inverse correlation of the 25(OH)D level and the stage of coronary atherosclerosis. Deficiency of 25(OH)D affects the levels of TC, LDL-C and TG.
