Heart Score Estimation by Specialized Nurses in a Greek Urban Population.

AIMS: Specialized nurses estimated the HeartScore in an urban Greek population by recognizing cardiovascular disease (CVD) risk factors in the setting of the Onassis Cardiovascular Prevention Program (OCPP). They also provided nursing consultation and assessed the clinical and biochemical characteristics of the studied population. METHODS AND RESULTS: Individuals were recruited through TV announcements and via the website of the Onassis Cardiac Surgery Centre. All participants visited the Onassis Cardiac Centre from 20 September to 30 October 2011. Overall, 2,145 individuals were included in the study. CVD risk was calculated by the HeartScore and serum total cholesterol was measured (mean: 193±43 mg/dl). Although 33% of the participants reported dyslipidaemia, only 17% were on hypolipidaemic treatment. Hypertension and dyslipidaemia frequency increased with age. CONCLUSION: In the present study, specialized nurses estimated the HeartScore in a Greek urban population. The majority of the studied population was undiagnosed and untreated. These results highlight the necessity for both primary and secondary prevention programs that can be carried out by specialized nurses. Such programs may improve the diagnosis and treatment of CVD risk factors; early initiation and optimization of therapy as well as management of drug intolerance (e.g. statins) can contribute to CVD risk reduction.

Gene polymorphisms and thyroid function in patients with heart failure.

We evaluated nuclear factor kappa B {NFkB, rs28362491 [-94ins/delATTG (W/D)]} and angiotensin converting enzyme {ACE; rs1799752 [Ins(I)/Del(D)]} gene polymorphisms and their correlation with thyroid function in patients with heart failure (HF). Peak oxygen uptake (VO(2)) was evaluated (by Weber classification) during a symptom-limited cardiopulmonary exercise test in 194 patients. Thyroid-stimulating hormone, triiodothyronine (T3), thyroxine (T4), and free (F) T3 and FT4 were also measured. According to their cardiovascular (CV) capacity, patients were subdivided into four groups: group A included patients with peak VO(2) >20 ml/kg/min, group B 16-20 ml/kg/min, group C 10-16 ml/kg/min, and group D 6-10 ml/kg/min. Patients were also genotyped for NFkB and ACE genetic variants. T3 was increased and FT3 was decreased for every raise in Weber's classification (p = 0.007 and p = 0.012, respectively). Del carriers had elevated FT3 levels compared with Ins carriers (p = 0.021). Patients with II genotype had elevated T4 levels compared with ID genotype (p = 0.044). Both T4 and FT4 were decreased in D allele carriers (p = 0.007 and p = 0.045, respectively). Thyroid hormones correlated with CV capacity. Associations between the NFkB and ACE gene polymorphisms and thyroid hormones levels were also observed. Further larger studies are required to clarify genes contribution in HF.

The frequency of 4 common gene polymorphisms in nonagenarians, centenarians, and average life span individuals.

Single nucleotide polymorphisms of angiotensin-converting enzyme (ACE) such as rs1799752, nuclear factor kappa B (NFkB) such as rs28362491 and cholesteryl ester transport protein (CETP) such as rs708272 (TaqB1) and rs5882 (I405V) were evaluated in nonagenarians, centenarians, and average life span individuals (controls). The study population (n = 307; 190 nonagenarians, 12 centenarians and 105 middle-aged controls) was genotyped for ACE, NFkB, and CETP genetic variants. The age of nonagenarian and centenarian group ranged between 90 and 111 years; centenarians and controls age ranged from 99 to 111, and from 18 to 80 years, respectively. The I carriers of ACE I/D gene were fewer in nonagenarians compared to centenarians (37.6% vs 62.5%, P = .016). The I carriers of ACE gene were more frequent in centenarians compared to controls (62% vs 41%, P = .045). No differences in frequency of common NFkB and CETP genotypes between patients with exceptional longevity and middle-aged patients were observed.

The role of common variants of the cholesteryl ester transfer protein gene in left main coronary artery disease.

BACKGROUND: The cholesteryl ester transfer protein (CETP) has a central role in the lipid metabolism and therefore may alter the susceptibility to atherosclerosis. METHODS: The DNA of 471 subjects [133 subjects with angiographically documented left main coronary artery disease (LMCAD), 241 subjects with more peripheral coronary artery disease (MPCAD) and 97 subjects self reported healthy (Controls)] was analyzed for the frequency of TaqIB and I405V polymorphisms in the gene coding CETP. RESULTS: There is no significant difference in CETP allele frequency or genotype distribution among LMCAD and MPCAD patients although there is statistical difference between LMCAD and Controls (p = 0.001). Specifically, patients with LMCAD and B1B1 genotype of TaqIB polymorphism were more frequent present compared to Controls (33.8% vs 22.9%, respectively). The frequency of B2B2 genotype was 3 times lower in the LMCAD group compared to Controls (10.5% vs 30.2%, respectively). In the LMCAD group the frequency of B1 allele compared to Controls was higher (62% vs 46%, respectively, p = 0.001). The relationship between TaqIB gene polymorphism and the LMCAD was independent of lipid profile, with the exception of apolipoprotein A. CONCLUSIONS: These findings indicate that the TaqIB polymorphism may have potential importance in screening individuals at high risk for developing CAD. However, this polymorphism cannot distinguish between LMCAD and MPCAD. Further prospective investigations in larger populations are required to confirm these findings.
