RESUMEN
BACKGROUND: Metabolic syndrome (MetSy) is characterized by the presence of obesity, hypertension, altered glucose metabolism, and/or increased non-HDL cholesterol. This study aimed at elucidating the association between obesity with subclinical target organ damage and biochemical parameters included in MetSy pathogenesis. METHODS: This study included 130 apparently healthy subjects. Plasma levels of oxidized-LDL-cholesterol (ox-LDL-Chol), nitric oxide (NO) metabolites, inducible NO synthase (iNOS), and plasminogen activator inhibitor-1 (PAI-1) were measured. Non-invasive assessment of liver disease included fatty liver index (FLI) and nonalcoholic fatty liver disease (NAFLD) fibrosis score. Carotid artery plaques were assessed by color Doppler imaging. RESULTS: A total of 65 patients with MetSy were included in the MetSy group, while 65 without MetSy entered the control group. Ox-LDL-Chol levels were higher in the MetSy group compared to the control group, regardless of obesity. Levels of NO metabolites were similar in obese and non-obese patients with MetSy, but lower than in the control group. Obese patients with MetSy had higher iNOS values compared to non-obese ones, with similar PAI-1 levels. NAFLD was present in all obese patients with MetSy compared to 70% of non-obese subjects. Hypertension, higher values of waist-to-hip ratio, PAI-1, and remnant cholesterol were associated with NAFLD. Finding of asymptomatic carotid plaques was associated with patients' age, hypertension, and higher waist-to-hip ratio. CONCLUSION: MetSy and obesity significantly alter the levels of NO metabolites, iNOS, ox-LDL-Chol, and PAI-1. High prevalence of NAFLD in obese patients with MetSy requires active screening and treatment of potential risk factors.
RESUMEN
The aim of this study was to compare QT dispersion (QTd) and echocardiographic parameters in male athletes competing across different sports (long-distance running, volleyball, football, powerlifting, and bodybuilding) and a control population. Significant moderate-strong differences (p < 0.001, [Formula: see text] = 0.52-0.71) were found in corrected QTd, intraventricular septal wall thickness (ISWT), posterior wall thickness (PWT), relative wall thickness (RWT) and LV (left ventricular) index between groups. Corrected QTd, ISWT, PWT, and RWT were significantly (p < 0.001) higher in powerlifters and bodybuilders compared to other athlete groups and controls. While all athlete groups displayed a significantly higher LV index (p < 0.05) compared to controls, corrected QTd was significantly lower (p < 0.001) only in long-distance runners, volleyball athletes, and football athletes compared to controls. Normal or eccentric LV hypertrophy (LVH) was observed in most long-distance runners (58% and 33%), volleyball athletes (50% and 50%), and football athletes (56% and 41%). In contrast, concentric LVH was observed in most powerlifters (58%) and bodybuilders (54%). Advanced LVH, predominantly concentric in nature, appears to be accompanied with increased QTd in powerlifters and bodybuilders. On the other hand, runners, volleyball athletes, and football athletes experienced LVH toward the upper threshold of the normal reference range alongside reduced QTd compared to other groups.

BACKGROUND: Electrocardiography is the first-choice technique for detecting left ventricular hypertrophy in patients with arterial hypertension. It is necessary to know the probable outcome for every patient during the treatment, with the aim of improving cardiovascular event prevention. HYPOTHESIS: Certain electrocardiographic criteria for left ventricular hypertrophy may predict outcomes of patients with left ventricular hypertrophy during a 15-year follow-up. METHODS: Fifteen-year prospective study of 83 consecutive patients (53 male and 30 female; mean age 55.3 ± 8.1) with echocardiographic left ventricular hypertrophy (left ventricular mass index 170.3 ± 31.6 g/m2 ). Electrocardiographic left ventricular hypertrophy was determined by means of Gubner-Ungerleider voltage, Lewis voltage, voltage of R wave in aVL lead, Lyon-Sokolow voltage, Cornell voltage and Cornell product, voltage RV6 and RV5 ratio, Romhilt-Estes score, Framingham criterion and Perugia criterion. RESULTS: One or more composite events were registered in 32 (38.5%) patients during 15-year follow-up. Positive Lyon-Sokolow score (17.6% vs. 47.3%; P < 0.05), Lewis voltage (9.8% vs. 21.9%; P < 0.05), Cornell voltage (15.7% vs. 37.5%; P < 0.05), and Cornell product (9.8% vs. 34.4%; P < 0.01) were more frequent in a group of patients with composite events. Odd ratio for Cornell product was 4.819 (95% CI 1.486-15.627). CONCLUSION: Patients with echocardiographic left ventricular hypertrophy who had positive Lewis voltage, Lyon-Sokolow voltage, Cornell voltage, and Cornell product showed worse 15-year outcome. The strongest predictor of cardiovascular events was positive result of Cornell product.

Background and objectives: A long-term therapeutic strategy in hypertensive patients equally depends on measured arterial blood pressure values and total determined cardiovascular risk. The aim of the adequate hypertensive patient treatment is both the reduction in arterial blood pressure and the reduction of all preexisting modifiable risk factors, prevention of target organs damage, and adverse cardiovascular events. The aim of this study was to determine independent predictors of cardiovascular events in patients with hypertension and high cardiovascular (CV) risk, and whether the modifiable risk factors could affect long-term prognosis in the studied population. Materials and Methods: This prospective study included 142 hypertensive patients (65% females), mean age 63.1±8 years, with high CV risk. Each participant was followed for 6.2 years. Results: During the follow-up period, the incidence of non-fatal and fatal CV events was 19.7%, CV mortality 7%, and total mortality 9.9%. Our multivariate analysis showed that plaques in both carotid arteries (p = 0.042), diabetes mellitus (p = 0.042) and cholesterol at the beginning of the study (p = 0.016) were significantly associated with an increased risk of CV events. Patients' age (p = 0.009), intima-media thickness (p = 0.001) and diabetes mellitus (p = 0.042) were significantly associated with an increased risk of CV mortality, and age (p = 0.007) and cholesterol (p = 0.002) were independent variables significantly associated with increased total mortality rates. Conclusions: The results of the present study showed that the main predictors of adverse CV events in high-risk hypertensive patients were years of age, cholesterol levels, diabetes, intima-media thickness, and carotid arteries plaques.

The goal of the present study was to determine the prevalence of hyperuricemia in patients with coronary artery disease (CAD), within three months after coronary events. Also, we aimed to determine whether the presence of hyperuricemia holds correlation with severe CAD, overall heart functioning and risk factors for CAD. The study included 505 consecutive CAD patients, 385 males and 120 females, aged 60.9 ± 9.6 years, with a mean body mass index (BMI) 28.0 ± 3.7 kg/m2. All patients were admitted to specialized cardiovascular rehabilitation within three months post-acute myocardial infarction (AMI) without revascularization (32.6%), percutaneous coronary intervention (PCI) with myocardial infarction (32.1%) and with coronary bypass graft (35.3%). The mean value of serum acidum uricum (SUA) was 345.5 ± 100.3 µmol/L, where 115 (22.8%) patients had asymptomatic hyperuricemia. Patients with asymptomatic hyperuricemia had significantly higher average number of risk factors, lower HDL cholesterol and higher creatinine and triglycerides levels, lower ejection fraction (EF). Multivariate stepwise analysis revealed that five parameters were capable to predict SUA levels. We can conclude that in patients with CAD, SUA levels are independently associated with BMI, triglyceride and creatinine levels and negatively with EF. Thus, one can say that asymptomatic hyperuricemia is not significantly associated with the severity of CAD.

BACKGROUND: The impact of overt diabetes and poor glycemic control on the risk of cardiovascular disease is well established. Among patients with type 2 diabetes, several studies demonstrated a significant increase in coronary artery disease-related death and cardiovascular events associated with HbA1c levels of greater than 7% compared with lower levels. Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are a novel class of anti-diabetic drugs that lower blood glucose levels through the suppression of renal glucose reabsorption thereby promoting renal glucose excretion. OBJECTIVES: To summarize data on the potential mechanisms of SGLT-2 inhibition that could exert cardiovascular benefits in patients with diabetes mellitus. METHOD: We conducted an in-depth literature search of SGLT-2 inhibitors and potential cardiovascular benefits and mechanisms that mediate those effects. RESULTS: In diabetes, expression of the SGLT-2 genes is up-regulated and renal threshold increased, resulting in increased glucose reabsorption from glomerular filtrate, reducing urinary glucose excretion and worsening hyperglycemia. SGLT-2 inhibition should offer potential cardiovascular protection in diabetic patients via attenuating hyperglycemia, blood pressure, body weight, hyperuricemia, and diabetic nephropathy. CONCLUSION: The initial data of SGLT-2 inhibitors suggest beneficial effects on cardiovascular risk among patients with diabetes mellitus. Several mechanisms are hypothesized to mediate the abovementioned benefits. Future randomized, controlled studies are needed in order to unveil the contribution of each mechanism to these outcomes.

AIMS: The aim of this study is to evaluate the impact of metabolic syndrome (MetS) on clinical severity and long-term prognosis in patients with myocardial infarction with ST-segment elevation (STEMI). METHODS: We examined 507 patients with STEMI, who were admitted for primary percutaneous coronary intervention classified according to the presence of MetS using American Heart Association and the National Heart, Lung, and Blood Institute definition. After applying these criteria, the patients were categorized into groups as patients with MetS and without MetS. We compared baseline characteristics, clinical findings, and outcomes between these groups. During the 48-month follow-up, we collected data about major adverse cardiac events (MACE) and mortality. RESULTS: The MetS group comprised 217 patients with MetS (mean age = 60.71 ± 11.52 years; 59 females), while the control group comprised 290 subjects (mean age = 57.50 ± 10.95 years; 54 females). The patients with and without MetS had similar parameters of clinical severity of STEMI but differed in severe coronary artery disease. During the follow-up period, a significantly higher percentage of myocardial infarction (6.91% vs 2.06%) and new revascularization (16.59% vs 8.97%) was recorded in the MetS group. On multivariate analysis, MetS was independently associated with MACE (HR = 1.834, 95% CI = 1.162-2.896, p = 0.009) but not with mortality (HR = 1.603, 95% CI = 0.864-2.973, p = 0.134). Among cardiovascular events that compose MACE, MetS was associated with new revascularization (HR = 2.204, 95% CI = 1.273-3.815, p=0.005). CONCLUSION: The presence of MetS in patients with STEMI is an independent risk factor for MACE, and this syndrome is strongly associated with new revascularization.

OBJECTIVES: We sought to determine the predictive power of metabolic syndrome (MS) definitions on the prognosis in patients with myocardial infarction with ST-segment elevation (STEMI). METHODS: We prospectively included 507 patients with STEMI who were admitted for primary percutaneous coronary intervention and could be identified for MS using the AHA-NHLBI, NCEP-ATP III and IDF definitions. After applying these criteria, we divided the group in patients with MS and without MS; we compared baseline characteristics, clinical findings and outcomes among these patients. RESULTS: The prevalence of MS was lowest with the NCEP-ATP III definition (37.87%), followed by the AHA-NHLBI definition (42.80%) and highest when using the IDF definition (44.38%). During follow-up, the occurrence of new myocardial infarction and new revascularization was significantly higher in patients with MS. Only in a group of patients with MS according to the NCEP-ATP III definition, a higher number of strokes were recorded. Multivariate analysis shows that MS according to the NCEP-ATP III definition was an independent predictor for MACE (OR 1.830, 95% CI 1.238-2.704, p = .002) but not for mortality. CONCLUSION: Metabolic syndrome according to the NCEP-ATP III definition was associated with increased risk of the development of new cardiovascular events among the patients with STEMI.

Hypertension has a central role in cardiometabolic disease and is usually associated with metabolic disorders, such as insulin resistance, obesity, and dyslipidemia. Hyperinsulinemia may increase cardiovascular (CV) risk through its promotion of hypertension, which is possibly a result of chronic enhancement of sympathetic nervous system activity, stimulation of the renin-angiotensin-aldosterone system leading to increased renal tubular sodium reabsorption, modulating cation transport, or inducing vascular smooth muscle cell hypertrophy. The body mass index value is associated with hypertension, but additional analyses showed that the strongest link existed between visceral obesity and hypertension. In a cross-sectional study, we have already shown that pulse pressure (PP) amplification, heart rate (HR), and pulse valve velocity (PWV), but not augmentation index (Aix), are increased in patients with metabolic syndrome (MS). The basis of therapy for hypertension in MS lies in a changed way of life, involving caloric intake reduction, increased quality of food, increased physical activity, and medicamentous therapy. Such a therapy has a favorable impact not only on blood pressure (BP), but on all the components of MS, and is able to delay the onset of diabetes.

BACKGROUND: Persistent and adequate treatment of patients with arterial hypertension leads to more favorable disease outcome. HYPOTHESIS: Aside for the present left ventricular hypertrophy (LVH), there are other non-invasive parameters which can represent additional predictors of unfavorable prognosis in patients with essential arterial hypertension during the 10-year follow-up. METHODS: A hypertensive group with LVH (124 patients; age 57.0 ± 8.0; 84 males and 40 females) was included in the study and examined noninvasively. Patients used regular medication therapy during the follow-up period. RESULTS: During the 10-year follow-up period, unfavorable outcome was recorded for 40 (32.3%) patients. Patients with unfavorable outcome had higher baseline values of left ventricular mass index (178.9 ± 29.5 g/m2 vs 165.5 ± 29.5 g/m2 ; P < 0.05) and QTc dispersion (64.1 ± 24.7 ms vs 54.8 ± 19.4 ms; P < 0.05). Frequency of positive Cornell product was higher in the group of patients with unfavorable outcome (35% vs 22.2%; P < 0.01). Positive Lyon-Sokolow score did not show statistical significance (25% vs 11.9%; P = 0.06). Cornell product (ß = 0.234; P < 0.01) and QTc dispersion >65 ms (ß = 0.184; P < 0.05) had prognostic significance in LVH (multiple regression analysis: R = 0.314, R = 0.099, adjusted R = 0.084, standard error of the estimate = 0.449, P < 0.05). CONCLUSIONS: Patients with a positive Cornell product and larger QTc dispersion had more unfavorable 10-year outcomes compared with other patients with LVH.

Our aim was to compare left ventricular (LV) deformation in subjects with masked hypertension (MH) to normotensive and sustained hypertensive patients. This cross-sectional study included 185 untreated subjects who underwent 24-hour ambulatory blood pressure (BP) monitoring and complete two-dimensional echocardiographic (2DE) examination including multilayer strain analysis. MH was diagnosed if clinic BP was normal (<140/90 mm Hg), and 24-hour BP was increased (≥130/80 mm Hg). 2DE LV longitudinal and circumferential strains gradually and significantly decreased from normotensive controls across MH individuals to sustained hypertensive patients. 2DE radial strain was not different between groups. 2DE longitudinal and circumferential endocardial and midmyocardial layer strains progressively decreased from normotensive control to sustained hypertensive individuals. Longitudinal and circumferential epicardial layer strains were lower in sustained hypertensive patients than in normotensive controls. Clinic and 24-hour systolic BP were associated with 2DE LV longitudinal endocardial strain, midmyocardial strain, and 2DE circumferential endocardial strain in the whole-study population independent of LV structure and diastolic function. MH significantly affect LV deformation assessed by 2DE traditional strain and 2DE multilayer strain. Clinic and 24-hour systolic BP were associated with LV mechanics evaluated with comprehensive 2DE strain analysis independent of LV structure and diastolic function.

INTRODUCTION: Cardiovascular (CV) diseases and bone fractures due to osteoporosis are the leading causes of death in the elderly. OBJECTIVE: The aim of this study was to demonstrate a correlation between the overall risk for CV events, and low bone density in postmenopausal women, and its impact on the incidence of serious CV events. METHODS: Our prospective study involved 300 postmenopausal women. All the examinees were divided into three groups based on their measured bone density: Group I--84 examinees with osteoporosis; Group II--115 examinees with osteopenia; and Group III--101 examinees with normal bone density. In all examinees the overall ten-year risk for a fatal CV event was calculated using the SCORE system tables. RESULTS: After a 36-month follow-up, CV events occurred in 19 (6.3%) examinees. Significant differences in the incidence of CV events were demonstrated between the patients with osteoporosis, osteopenia, and normal bone density (χ2 = 28.7; p < 0.001), as well as between those with a high and low CV risk (χ2 = 22.6; p < 0.001). Multivariate logistic regression analysis showed that smoking (OR: 2.23; 95% CI: 1.02 to 6.19; p = 0.035), and increase of overall CV score (OR: 1.36; 95% CI: 1.17 to 1.58; p < 0.001) are associated with increased CV event risk, while the increase of T score value is associated with decreased risk of CV event (OR: 0.42; 95% CI: 0.25 to 0.73; p = 0.002). CONCLUSION: Measurement of bone density with a standard assessment of the total CV risk could be useful for selecting women who need intensive prevention and treatment of atherosclerosis.

European Society of Cardiology Guidelines cite results of meta-analysis that the use of calcium channel blockers results in fewer angina episodes per week vs. long-acting nitrates. Moreover, we listed 12 reasons more to prefer amlodipine over long-acting nitrates, especially in stable angina pectoris patients with arterial hypertension. It may be the way to decrease polypharmacy without loosing efficacy. Some important advantages of amlodipine versus long-acting nitrate(s) are: amlodipine also treats hypertension, it helps reducing hypertensive target organ damages (e.g. left ventricular hypertrophy) and prevents morning blood pressure surge. Moreover, amlodipine can be given once daily (which improves adherence), it produces neither tolerance nor rebound, it has less side effects.
RESUMEN
INTRODUCTION: Regardless of other known factors, left ventricular hypertrophy is considered to be a significant factor which correlates with the risk of cardiovascular complications. In practice, it is very important to predict the outcome for every patient at the beginning of the treatment. OBJECTIVE: The aim of the study was to follow the predictive value of non-invasive parameters obtained at the beginning of the study in patients with essential arterial hypertension and left ventricular hypertrophy who were treated by regular therapy through a five year follow-up period. METHODS: Ninety patients (average age 55) with essential hypertension and left ventricular hypertrophy were examined. All patients were studied at baseline after temporary discontinuation of previous antihypertensive therapy. The follow-up period started at the baseline examination and lasted for five years. Adverse cardiovascular events occurred in 15 (16.7%) patients. RESULTS: Non-invasive parameters were tested by stepwise multiple regression analysis. Three examined parameters had predictive value: QTc interval dispersion (beta = 0.325, p = 0.001), septal wall thickness (beta = 0.294, p = 0.003) and low increase of the heart rate during exercise testing (beta = -0.202, p < 0.04). For this model, adjusted R square = 0.203; F3,84 = 8.406, p < 0.0001. CONCLUSION: In spite of regular medical treatment, patients with larger QTc dispersion, greater septum thickness and lower increase of heart rate during exercise testing showed worse outcome through the follow-up period. These patients should be recognized as early as possible and treated more aggressively.

INTRODUCTION: Considering that dyslipidaemia is an important factor for cardiovascular diseases, target lipid levels are rarely reached in everyday clinical practice. OBJECTIVE: The objective of this study was to evaluate how often we achieve the treatment goals for the lipid parameters in the diabetic and non-diabetic patients after the previous myocardial infarction (MI). METHODS: The survey included 118 patients (84 males and 34 females), mean age 59.38 +/- 9.86 years, 34 (28.8%) of them diabetics, with the history of MI in the previous 3 years. The patients were selected from the database of multicentre prospective interventional study "Secondary prevention of coronary heart disease and cerebrovascular diseases", conducted in 2005 on 1,189 patients in Serbia. The patients were further followed in the period from 18 (5th visit) and 36 months (6th visit) after inclusion into the study from 2005-2008. Their lipid status, the use of lipid-lowering drugs, and the independent prognostic factors for major adverse coronary events were identified. In the beginning of the study, all patients were informed about the importance of lifestyle change and active approach to treatment. The accomplishment of secondary preventive measures was estimated on the basis of the European guidelines on secondary prevention of the coronary heart disease. RESULTS: Three years after introduction of the preventive measures, diabetics had a higher prevalence of the target levels of the total cholesterol (21.2% vs. 7.6%) and HDL-cholesterol than non-diabetics (100% vs. 87.3%) (p < 0.05). Non-diabetics had significantly higher prevalence of the target levels of LDL-cholesterol than diabetics (19% vs. 3%) (p < 0.05). No significant differences were found in the prevalence of the treatment goals of triglycerides in diabetic (42.4%) and non-diabetic patients (60.8%) (p > 0.05). At the end of the study, after applying secondary prevention measures, 27.3% of diabetics did not use lipid-lowering drugs. The percentage of non-diabetics using no lipid-lowering drugs was lower (20.3%), but the difference was not statistically significant (p > 0.05). By using the method Enter Cox regression multivariant analysis, the change in the level of triglycerides, total and LDL-cholesterol were singled out as independent prognostic factors for major adverse coronary events. CONCLUSION: Our study has shown high prevalence of increased plasma concentrations in the total, LDL-cholesterol and triglycerides and low plasma concentrations of HDL-cholesterol, as well as the insufficient use of lipid-lowering drugs in diabetic and non-diabetic patients with previous MI. Decreasing the total cholesterol and increasing the HDL-cholesterol are significant, decreasing of triglycerides and LDL-cholesterol does not suffice. Therefore, secondary prevention measures of cardiovascular events should be intensified, especially in patients with diabetes.

BACKGROUND: The EUROASPIRE surveys showed high rates of modifiable cardiovascular risk factors in patients with coronary heart disease, identified after coronary artery bypass graft, percutaneous coronary intervention or myocardial infarction, with time trends in preventive cardiology over more than a decade. AIM: The aim of this study was to test the implementation of European recommendations for cardiac rehabilitation and secondary risk prevention programmes in the population of coronary heart disease patients from Serbia. SUBJECTS AND METHODS: A total of 665 consecutive coronary heart disease patients (432 men, 233 women, aged 59.43 +/- 11.62 years), admitted for specialized cardiovascular rehabilitation, interviewed and examined in relation to the presence of coronary risk factors and administration of secondary prevention measures, were enrolled in the study. RESULTS: High rates of smoking (27.67%), central obesity (58.05%), physical inactivity (61.50%) and adverse dietary habits (61.50%) were observed, as well as low frequency of patients who have reached recommended targets for waist circumference (41.95%), total cholesterol (40%), LDL-cholesterol (39.25%), HDL-cholesterol (59.69%) and triglycerides (59.25%), while systolic (82.26%) and diastolic blood pressures (95.49%) were well regulated. A significantly lower rate of achieved therapeutic targets, despite widely used cardioprotective drugs, was observed in diabetic patients and patients with the metabolic syndrome. CONCLUSION: The results have shown a low proportion of coronary heart disease patients, especially with diabetes mellitus and metabolic syndrome, who reached the recommended therapeutic targets for cardiometabolic risk profile parameters, in spite of widely used cardioprotective drugs, and therefore clearly demonstrated the compelling need for more effective lifestyle management in the secondary prevention of coronary heart disease.

BACKGROUND/AIM: Chest pain often indicates coronary disease, but in 25% of patients there is no evidence of ischemic heart disease using standard diagnostic tests. Beside that, cardiologic examinations are repeated several times for months. If other medical causes could not be found, there is a possibility that chest pain is a symptom of psychiatric disorder. The aim of this study was to determine the presence of psychiatric syndromes, increased somatization, anxiety, stress life events exposure and characteristic of chest pain expression in persons with atypical chest pain and coronary patients, as well as to define predictive parameters for atypical chest pain. METHOD: We compared 30 patients with atypical chest pain (E group) to 30 coronary patients (K group), after cardiological and psychiatric evaluation. We have applied: Mini International Neuropsychiatric Interiview (MINI), The Symptom Checklist 90-R (SCL-90 R), Beck Anxiety Invetory (BAI), Holms-Rahe Scale of stress life events (H-R), Questionnaire for pain expression Pain-O-Meter (POM). Significant differences between groups and predictive value of the parameters for atypical chest pain were determined. RESULTS: The E group participants compared to the group K were younger (33.4 +/- 5.4: 48.3 +/- 6,4 years, p < 0.001), had a moderate anxiety level (20.4 +/- 11.9: 9.6 +/- 3.8, p < 0.001), panic and somatiform disorders were present in the half of the E group, as well as eleveted somatization score (SOM > or = 63-50%: 10%, p < 0.01) and a higher H-R score level (102.0 +/- 52.2: 46.5 +/- 55.0, p < 0.001). Pain was mild, accompanied with panic. The half of the E group subjects had somatoform and panic disorders. CONCLUSION: Somatoform and panic disorders are associated with atypical chest pain. Pain expression is mild, accompained with panic. Predictive factors for atypical chest pain are: age under 40, anxiety level >20, somatization > or =63, presence of panic and somatoform disorders, H-R score >102, and a lack of positive diagnostic test of coronary disease. Defining of these parameters could be useful for early psychiatric evaluation of persons with atypical chest pain.

Practical recommendations for the regulation of hyperlipoproteinemia and the prevention of coronary disease and scoring systems for coronary disease risk estimation are based on the results of epidemiologic studies and international consensus guidelines. According to the Framingham point score the risk was defined as an absolute 10 year probability of myocardial infarction and coronary death, while the PROCAM function of risk was based on cardiovascular events: fatal and non-fatal myocardial infarction and sudden coronary death. The Third European Joint Task Force and other societies for the prevention of cardiovascular diseases revise the joint European guidelines and the recommendations for national population strategies. Global coronary disease risk is nowadays in Europe based on the SCORE system. The risk is defined as an absolute 10 year probability of afatal cardiovascular event, and high risk cut-off is at 5%.

AIM: The aim of the present study was to investigate the prevalence of the PC-1 121Q allele and to test its association to cardiovascular risk factors in type 2 diabetes mellitus (DM) patients. METHODS: A total of 103 unrelated Caucasians from Serbia, including 71 DM patients without CHD (aged 59.4 +/- 8.9 years, with a mean body mass index (BMI) of 33.3 +/- 4.8 kg/m2) and 32 DM patients who suffered from coronary heart disease (DM+CHD) (aged 59.3 +/- 8.0 years, with a mean BMI of 30.37 +/- 3.71 kg/m2), were genotyped for PC-1 K121Q using a mutagenic separated PCR assay. RESULTS: The prevalence of the PC-1 121Q allele was significantly higher in DM+CHD, compared to DM (P < 0.001) and control (P < 0.001) groups, since it was found in 10 (14%) DM patients, 13 (41%) DM+CHD patients and 10 (17%) control subjects. When the association of PC-1 121Q allele and the risk of suffering from CHD were assessed within the DM group in a binary logistic regression model adjusting for age and sex, PC-1 121Q allele carriers had a 76% lower risk (OR 0.24; 95% CI: 0.08-0.67, P = 0.006) for developing CHD compared to subjects who exhibited PC-1 wild-type. CONCLUSION: The prevalence of the PC-1 121Q allele was significantly higher in type 2 diabetic patients who suffered from CHD, compared to type 2 diabetic patients without CHD. However, after a binary logistic regression model analysis, adjusting for age and sex., PC-1 121Q allele carriers had a 76% lower risk (OR 0.24; 95% CI: 0.08-0.67, P = 0.006) for developing CHD compared to subjects who exhibited PC-1 wild-type. Since these data were cross-sectional, the potential patient selection and survival bias, as well as community underdiagnosis of DM and CHD, could most likely substantially underestimate the genetic influence.
