Abstract Background Diabetes is a risk factor for coronary heart disease (CHD), but further risk stratification in patients with diabetes is necessary to improve the prediction and prevention of cardiovascular events and deaths. Growth differentiation factor-15 (GDF-15) is a stress-responsive cytokine, which plays an important role in the regulation of the inflammatory response, growth and cell differentiation. Elevated GDF-15 was found in various diseases including diabetes and stable CHD, and was reported to predict mortality and cardiovascular events in general or established CHD population. However, the prognostic value of GDF-15 in suspected or known CHD patients with diabetes is unknown. Methods Serum GDF-15 levels were measured in 1,087 suspected or known CHD patients with diabetes undergoing elective coronary angiography, enrolled in the development of novel biomarkers related to angiogenesis or oxidative stress to predict cardiovascular events (ANOX) study, and followed up for 3 years. The primary outcome was all-cause death. The secondary outcomes were cardiovascular death, and major adverse cardiovascular events (MACE) defined as a composite of cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke. Results During the follow-up, 147 patients died from any cause, 47 died from cardiovascular disease, and 94 developed MACE. After adjustment for established risk factors, GDF-15 levels were significantly associated with all-cause death (hazard ratio [HR] for 1-SD increase, 1.66; 95% confidence interval [CI], 1.48–1.86), cardiovascular death (HR, 1.63; 95% CI, 1.34–1.99), and MACE (HR, 1.41; 95% CI, 1.20–1.65). Even after incorporation of N-terminal pro-brain natriuretic peptide, contemporary sensitive cardiac troponin-I, and high-sensitivity C-reactive protein into a model with established risk factors, the addition of GDF-15 levels further improved the prediction of all-cause death (continuous net reclassification improvement [NRI], 0.344; 95% CI, 0.172–0.517; P<0.001; integrated discrimination improvement [IDI], 0.049; 95% CI, 0.026–0.072; P<0.001), but not that of cardiovascular death (NRI, −0.013; 95% CI, −0.300–0.274; P=0.931; IDI, 0.023; 95% CI, 0.003–0.043; P=0.026) or MACE (NRI, 0.059; 95% CI, −0.151–0.268; P=0.583; IDI, 0.005; 95% CI, −0.004–0.015; P=0.244). Conclusions In suspected or known CHD patients with diabetes undergoing elective coronary angiography, elevated GDF-15 levels may predict all-cause mortality independent of established risk factors and cardiovascular biomarkers.

Abstract Background Chronic kidney disease (CKD) is an independent risk factor for the development and progression of coronary heart disease (CHD). Growth differentiation factor-15 (GDF-15), a distant member of the transforming growth factor-β cytokine superfamily, plays a role in the initiation of inflammation in atherosclerotic lesions. Elevated GDF-15 was found in various diseases including CKD and stable CHD, and was reported to predict mortality and cardiovascular events in general or established CHD population. However, the prognostic value of GDF-15 in suspected or known CHD patients with CKD is unknown. Methods Serum GDF-15 levels were measured in 999 suspected or known CHD patients with CKD undergoing elective coronary angiography, enrolled in the development of novel biomarkers related to angiogenesis or oxidative stress to predict cardiovascular events (ANOX) study, and followed up for 3 years. The primary outcome was all-cause death. The secondary outcomes were cardiovascular death, and major adverse cardiovascular events (MACE) defined as a composite of cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke. Results During the follow-up, 154 patients died from any cause, 61 died from cardiovascular disease, and 96 developed MACE. After adjustment for established risk factors, GDF-15 levels were significantly associated with all-cause death (hazard ratio [HR] for 1-SD increase, 1.78; 95% confidence interval [CI], 1.57–2.00), cardiovascular death (HR, 1.88; 95% CI, 1.58–2.25), and MACE (HR, 1.54; 95% CI, 1.32–1.79). Even after incorporation of N-terminal pro-brain natriuretic peptide, contemporary sensitive cardiac troponin-I, and high-sensitivity C-reactive protein into a model with established risk factors, the addition of GDF-15 levels further improved the prediction of all-cause death (continuous net reclassification improvement [NRI], 0.401; 95% CI, 0.231–0.571; P<0.001; integrated discrimination improvement [IDI], 0.041; 95% CI, 0.021–0.062; P<0.001) and cardiovascular death (NRI, 0.297; 95% CI, 0.039–0.555; P=0.024; IDI, 0.032; 95% CI, 0.010–0.055; P=0.005), but not that of MACE (NRI, 0.138; 95% CI, v0.070–0.347; P=0.194; IDI, 0.012; 95% CI, −0.000–0.024; P=0.053). Conclusions In suspected or known CHD patients with CKD undergoing elective coronary angiography, elevated GDF-15 levels may predict all-cause and cardiovascular mortality independent of established risk factors and cardiovascular biomarkers.

Abstract Background Diabetes is a risk factor for coronary heart disease (CHD), but further risk stratification in patients with diabetes is necessary to improve the prediction and prevention of cardiovascular events and deaths. Vascular endothelial growth factor-D (VEGF-D) is a secreted glycoprotein that can act as lymphangiogenic and angiogenic growth factors through binding to its specific receptors, VEGFR-3 (Flt-4) and VEGFR-2 (KDR/Flk-1). VEGF-D signaling via VEGFR-3 plays an important role in lipoprotein metabolisms which may contribute to CHD. VEGF-D signaling has been used as a therapeutic target of human diseases such as lymphangioleiomyomatosis and refractory angina. Furthermore, in clinical settings, the VEGF-D level is already established as a diagnostic biomarker for lymphangioleiomyomatosis. However, the prognostic value of VEGF-D in suspected or known CHD patients with diabetes is unknown. Methods Serum VEGF-D levels were measured in 1,087 suspected or known CHD patients with diabetes undergoing elective coronary angiography, enrolled in the development of novel biomarkers related to angiogenesis or oxidative stress to predict cardiovascular events (ANOX) study, and followed up for 3 years.

Abstract Background Vascular endothelial growth factor-D (VEGF-D) is a secreted glycoprotein that can act as lymphangiogenic and angiogenic growth factors through binding to its specific receptors, VEGFR-3 (Flt-4) and VEGFR-2 (KDR/Flk-1). VEGF-D signaling via VEGFR-3 plays an important role in lipoprotein metabolisms which may contribute to coronary heart disease (CHD). Recent studies suggest that VEGF-D appears to be a biomarker of pulmonary congestion and heart failure in both dyspnea patients and the general population. However, the prognostic value of VEGF-D in suspected or known CHD patients with a history of heart failure is unknown. Methods Serum VEGF-D levels were measured in 253 suspected or known CHD patients with a history of heart failure undergoing elective coronary angiography, enrolled in the development of novel biomarkers related to angiogenesis or oxidative stress to predict cardiovascular events (ANOX) study, and followed up for 3 years. The primary outcome was all-cause death. The secondary outcomes were cardiovascular death, and major adverse cardiovascular events (MACE) defined as a composite of cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke. Results During the follow-up, 54 patients died from any cause, 24 died from cardiovascular disease, and 35 developed MACE. After adjustment for established risk factors, VEGF-D levels were significantly associated with all-cause death (hazard ratio [HR] for 1-SD increase, 1.44; 95% confidence interval [CI], 1.18–1.75), cardiovascular death (HR, 1.73; 95% CI, 1.32–2.25), and MACE (HR, 1.49; 95% CI, 1.14–1.89).

Abstract Background The lymphatic system has been suggested to play an important role in cholesterol metabolism and cardiovascular disease. Recently, we demonstrated that serum levels of vascular endothelial growth factor-C (VEGF-C), a central player of lymphangiogenesis, are inversely and independently associated with the risk of all-cause mortality in patients with suspected or known coronary heart disease (CHD). However, the prognostic value of VEGF-C in patients with suspected but no history of CHD is still unclear. Methods Serum VEGF-C levels were measured in 1,717 patients with suspected but no history of CHD undergoing elective coronary angiography, enrolled in the development of novel biomarkers related to angiogenesis or oxidative stress to predict cardiovascular events (ANOX) study, and followed up for 3 years. The primary outcome was all-cause death. The secondary outcomes were cardiovascular death, and major adverse cardiovascular events (MACE) defined as a composite of cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke. Results During the follow-up, 161 patients died from any cause, 50 died from cardiovascular disease, and 104 developed MACE. After adjustment for established risk factors, VEGF-C levels were significantly and inversely associated with all-cause death (hazard ratio [HR] for 1-SD increase, 0.69; 95% confidence interval [CI], 0.58–0.83) and cardiovascular death (HR, 0.72; 95% CI, 0.52–0.998), but not with MACE (HR, 0.91; 95% CI, 0.74–1.13). Even after incorporation of N-terminal pro-brain natriuretic peptide, contemporary sensitive cardiac troponin-I, and high-sensitivity C-reactive protein into a model with established risk factors, the addition of VEGF-C levels further improved the prediction of all-cause death (continuous net reclassification improvement [NRI], 0.282; 95% CI, 0.121–0.443; P<0.001; integrated discrimination improvement [IDI], 0.009; 95% CI, 0.003–0.016; P=0.005), but not that of cardiovascular death (NRI, 0.178; 95% CI, r=−0.103–0.458; P=0.214; IDI, 0.004; 95% CI, r=−0.002–0.009; P=0.194) or MACE (NRI, 0.037; 95% CI, r=−0.162–0.235; P=0.717; IDI, 0.000; 95% CI, r=−0.0004–0.0005; P=0.872). Conclusions In patients with suspected but no history of CHD undergoing elective coronary angiography, a low VEGF-C value may predict all-cause mortality independent of established risk factors and cardiovascular biomarkers.

Obstructive Sleep

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.

OBJECTIVE: Recent evidence indicates that peroxisome proliferator-activated receptor-gamma (PPARgamma) is expressed at high levels in foam cells of atherosclerotic lesions, that PPARgamma agonists may directly modulate vessel wall function and that mutations in the PPARgamma-2 gene are associated with a reduced risk of coronary artery disease. METHODS: We investigated whether known variants in the PPARgamma-2 gene are associated with the occurrence of coronary heart disease (CHD) in 365 patients with type 2 diabetes, prospectively characterised for the presence or absence of CHD. The Pro115Gln, Pro12Ala, Pro467Leu, Val290Met mutations and two polymorphisms C478T and C161T of the PPARgamma-2 gene were examined using PCR, denaturing gradient gel electrophoresis and direct sequencing. RESULTS: The distribution of the Pro12Ala, Ala12Ala, C161T and T161T variants was not significantly different between patients with and without CHD, independent of the gender. The Pro12Ala (P=0.011) and the Ala12Ala (P=0.006) variant were associated with a higher body mass index (BMI) compared with the Pro12Pro genotype. A multiple logistic regression analysis introducing the typical risk factors for CHD (age, sex, hypertension, smoking, BMI >26 kg/m2, elevated low density lipoprotein cholesterol and haemoglobin A1c >7%) identified age >60, male gender, hypertension and a higher BMI, but not the PPARgamma-2 variants, as significant risk factors for CHD in our study groups. CONCLUSION: The PPARgamma-2 genotype was not associated with an increased or reduced risk of the occurrence of CHD and can therefore not be regarded as an independent risk factor for CHD in patients with diabetes mellitus.

The purpose of the study was to investigate the adherence to secondary prevention medications among patients with coronary heart disease and identify factors associated with it. Materials and methods. We examined 40 patients diagnosed with coronary heart disease of more than 50 years old, who were prescribed with optimal medication for 1 year during hospitalization. Patients` adherence was defined according to MMS-8 Morisky values for secondary prevention medications prescribed by doctors. Also, questionnaires about individual reasons of non-compliance and for individual patient`s opinion about importance and usefulness of knowledge according to risk factors of the increase of cardiovascular mortality were designed and proposed to the patients. Simple descriptive statistics were used to elucidate the characteristics of the patient population and results from individual adherence tools. Final score was analyzed and correlation between patients’ data and level of adherence to prescribed treatment were identified. A correlation matrix (using Spearman’s coefficient) was reviewed for any evidence of collinearity. Results and discussion. Our study demonstrated higher level of non-adherence with secondary prevention medications in patients with coronary heart disease (60.0%). This fact can be explained by the socioeconomic reasons, less informative strategies from the medical staff to the patients. Severe regress of adherence was demonstrated after discharge from the hospital due to subjective improvement of the patients` condition with absence of supervision by out-patient specialists. Demographic characteristics of the patients suggested that some non-modified factors can affect compliance with the prescribed treatment. Better adherence was demonstrated by female married patients with higher educational level, with family history about cardiovascular death. Also, too much prescribed medications with difficult regime of usage with non-adequate out-patient supervision may significantly decrease adherence causing development of complications which may lead to re-hospitalizations and cardiovascular death. Our investigation demonstrated also non-complete information of the patients about lifestyle and medical risk factors of the cardiovascular mortality increase. Conclusion. The results of our study can provide useful practical information on the prevalence and severity of non-adherence among patients with coronary heart disease. Analysis of the factors influencing the adherence demonstrated the main reasons from patients and healthcare professionals affecting the level of compliance with the prescribed treatment. The step towards improving adherence can be initiated by the healthcare professional to overcome the patient's concerns about the prescribed medication. It is important to continue personal monitoring of patients by healthcare professionals in the form of regular inspections of intentional and unintentional non-adherence, including factors and reasons that may change and lead to such behavior
