Effects of Almond Dietary Supplementation on Coronary Heart Disease Lipid Risk Factors and Serum Lipid Oxidation Parameters in Men with Mild Hyperlipidemia

Obstructive sleep apnoea syndrome (OSAS) increases the risk cardiovascular events regardless of the presence of previous cardiovascular disease. As both OSAS and coronary heart disease (CHD) have same risk factors it’s often difficult to quantify the proportion of each risk factor in developing cardiac events. The aim of this study was to evaluate the 10-year risk of developing a coronary heart disease (CHD) event or stroke in newly diagnosed OSAS patients. 65 patients diagnosed with OSAS over a period of four months in Oradea Sleep Laboratory were included. Demographic characteristics, anthropometric parameters, clinical and biochemical data, sleep disorder and daytime sleepiness assessment, results of polysomnography were collected in all patients. In 55 selected patients by age range from 34 to 74 years old, cardiovascular risk was assessed using Framingham score calculator. Statistical analysis was performed using SPSS-PC version 7.5 and Stata 10.The estimated 10-years risk of a CHD event was 18.97% (± 9.67) in all cases. It was higher in men (22.17% ± 9.24) compare to women (12.39% ± 6.92) and it was not significantly different by stages of OSAS severity (20.58% ±9.41 in patients with severe OSAS versus 15.4% in mild OSAS), suggesting that apnea hypopnea index is not a major confounding factor. Desaturation of oxygen is a better outcome to define the relation between OSAS and cardiovascular diseases. OSAS and cardiovascular risk factors increased risk for future adverse cardiovascular events related to the severity of oxygen desaturation.

Abstract Funding Acknowledgements Type of funding sources: None. The widespread use of coronary angiography (CAG) in patients with acute coronary syndrome led to the understanding that in some patients myocardial infarction (MI) occurs against angiographically unchanged or slightly modified coronary arteries (CA). In such cases, the so-called "type 2 IM" is diagnosed in some patients, however, to determine the true cause of MI, a modern method of investigation such as optical coherence tomography (OCT) is needed to visualize the intima of the CA and detect a minimal atherosclerotic process. The purpose of the study was to establish the etiology of MI without obstructive coronary artery disease (MINOCA) using OCT. Materials and methods 160 conclusions of the OCT were analyzed. In 9 (6%) cases, the study was conducted in patients who underwent proven MI (mean age 43,1 ± 13,2, 8 males, 1 female) who had no hemodynamically significant CA stenosis according to CAG data. Results in 2 cases (22%) patients had ST-elevation MI, thrombotic occlusion of the CA (in one case, thrombaspiration was performed). In both patients, spontaneous dissection of the intima of the unmodified CA was detected in the OCT. The remaining 7 patients had non-ST-elevation MI, and in 2 cases, a diagnosis of type 2 MI was established: in both patients, the atherosclerotic plaque was visualized, narrowing the lumen of the CA less than 50%, in one case MI developed against a background of the hypertensive crisis, in another - against a background of spasm of CA. In the remaining 5 patients, OCT revealed subintimal atheromatous, with elements of local dissection of the intima. Thus, in 78% of patients atherosclerosis of CA of different severity (from the subintimal deposition of lipids to the development of atherosclerotic plaque, narrowing the clearance of the SC by less than 50%) was diagnosed. In the analysis of risk factors for coronary heart disease (CHD), 57% of patients with atheromatous CA had more than 2 risk factors for CHD: 3 (42%) smoked, 5 (71%) - obesity, 4 (57% ) - had arterial hypertension, 3 (42%) had dyslipidemia, 1 (14%) had type 2 diabetes. In the group of patients with spontaneous intima dissection of the CA, 1 patient (woman) did not have CHD risk factors, the 2-nd suffered from obesity and hypertension. For all patients a lifestyle correction was recommended; statins, antiplatelets were prescribed, patients with spontaneous dissection of CA had the recommendation of examination in the medical-genetic center. Conclusion Based on the results of the study, in most cases, the cause of IMBOC development was an atherosclerotic lesion of the coronary arteries, which is not always visualized with standard coronary angiography. Basically, the patients were young and middle-aged. Most patients had different risk factors for coronary heart disease.
