Objective: The methodology for use of cardiac CT angiography (CTA) in low risk populations is not well defined. In order to present a reference for future studies, we present CTA methodology that is being used in an epidemiology study- the Multicenter AIDS Cohort Study (MACS). Methods: The Multicenter AIDS Cohort Study (MACS) is an on-going multicenter prospective, observational cohort study. The MACS Cardiovascular Disease substudy plans to enroll 800 men (n= 575 HIV seropositive and n=225 HIV seronegative) age 40-70 years for coronary atherosclerosis imaging using cardiac CTA. The protocol includes heart rate (HR) optimization with beta blockers; use of proper field of view; scan length limitation; prospective ECG-gating using the lowest beam voltage possible. All scans are evaluated for presence, extent, and com- position of coronary atherosclerosis, left atrial volumes, left ventricular volume and mass and non-coronary cardiac pathology. Results: The first 498 participants had an average radiation dose of 2.5±1.6 milliSieverts (mSv) for the cardiac CTA study. Overall quality of scans was fair to excellent in 98.6% of studies. There were three significant adverse events-two allergic reactions to contrast and one subcutaneous contrast extravasation. Conclusion: Cardiac CTA was safe and afforded a low effective radiation exposure to these asymptomatic research participants and provides valuable cardiovascular endpoints for scientific analysis. The cardiac CTA methodology described here may serve as a reference for use in future epidemiology studies aiming to assess coronary atherosclerosis and cardiac anatomy in low risk populations while minimizing radiation exposure.

Objective: In order to evaluate the utility of the heart rate performance index (HRPI), which is obtained by dividing HR mean by the difference of HR max and HR min in the context of Holter monitoring, we sought to determine whether there was any correlation or relationship between the HRPI and LVEF values as determined by echocardiography and to compare the HRPI between the study and control groups. Methods: This study is a cross-sectional, controlled observational study. Thirty-two patients with symptomatic or asymptomatic left ventricular systolic dysfunction (LVEF <45%) were included as study group and 32 subjects without chronic heart failure (CHF) were included as a control group. In the study group, 10 patients were in NYHA class I (31.2%), 12 - were in NYHA class II (37.6%) and 10 - were in NYHA class III (31.2%). Heart rate analysis was measured using 24-hour Holter ambulatory electrocardiography. To determine the HRPI, the difference between maximum (HR max) and minimum heart rate (HR min) was divided by mean heart rate (HR mean) (beats/minute): HRPI=(HR max-HR min) / HR mean. Statistical analysis was performed using t-test for independent samples, Mann-Whitney U test, Chi-square test, Kruskal-Wallis test, Pearson’s correlation and linear regression analyses. Results: The HRPI index value was markedly decreased [0.83 (0.58-1.1) and 1.10 (0.74-1.3), p<0.001] in the study group as compared to the control group. The data collected for the study group and the control group (n=64) demonstrated a positive correlation between the HRPI and LVEF (r=0.62, p<0.001) as well as a negative correlation between the HR mean and LVEF (r=-0.39, p<0.003). The HR mean was higher (80.2±11.3 and 75.2±6.7, p<0.007) and HR max-HR min (67.9±11.6 and 83.3±14.3, p<0.001) were lower in the study group as compared to the control group. Linear regression analysis demonstrated no significant relationship between LVEF and HRPI and other heart rate derivatives (unstandardized β=42.43 95% CI: 21.98-50.51, p=0.231). Conclusion: According to our findings, patients with CHF exhibited higher HR mean values, reduced HR max-min values and significantly decreased HRPI values. There is a positive correlation between HRPI and LVEF, a decreased HRPI is associated with a decreased LVEF, but there is no relationship between these two variables. Therefore HRPI values may represent a viable option for assessing daily exercise activity and potentially sympathetic activation in patients with CHF. The assessment of HRPI may be helpful the evaluation of CHF patients, as well as resting HR.

PMID: 23376650  doi: 10.5152/akd.2013.067  Pages 221 - 226
Objective: NT-pro-brain natriuretic peptide (NT-proBNP) has been shown to be an accurate diagnostic marker in patients with heart failure (HF). Adiponectin (Adp) levels are increased in HF but its diagnostic value is still uncertain in these patients. The study was designed to investigate the possible association of these markers in non-cachectic patients with newly diagnosed systolic heart failure. Methods: Fifty-seven systolic HF patients and 20 matched controls were enrolled in an observational cross-sectional study. Physical and echocardiographic examinations were performed and serum Adp, NT-proBNP, tumor necrosis factor-alpha (TNF-α) levels were measured. Study variables were compared between the groups. Correlation analyses were done and the diagnostic validity of the markers was compared with ROC analysis. Results: Adp and NT-proBNP levels were significantly higher in HF group (20.19±12.9 vs. 7.65±4.6 μg/mL; p<0.001 and 1051.74±606.2 vs. 222.53±65.6 pg/mL; p=0.002; respectively). TNF-α levels were similar between the groups (2.83±1.8 vs. 2.08±1.2 pg/mL; p=0.582). Correlation analysis showed significant association among Adp and NT-proBNP levels, (r=0.448; p<0.001), and left ventricular ejection fraction (LVEF) values (r=-0.466; p<0.001). The Adp and NT-proBNP showed comparable diagnostic performances with mean [95% confidence interval] areas under the curves of 0.857 (0.771-0.944) and 0.888 (0.815-0.960), respectively. Conclusion: There were significant correlation between Adp levels with NT-proBNP levels and LVEF values but no any association between Adp levels with body mass index values and TNF-α levels in patients with newly diagnosed systolic heart failure. The result may arouse suspicion about the hypothesis, which proposes that Adp levels simply reflects disease severity or cardiac cachexia in patients with HF.

PMID: 23376651  doi: 10.5152/akd.2013.068  Pages 227 - 234
Objective: Metabolic syndrome (MetS) is a strong predictor of cardiovascular events and coronary flow reserve (CFR), an indicator of microvascular function, has been found to be impaired in MetS. Aortic stiffness (AS) is a simple and effective method for assessing arterial elasticity. The aim of this study was to evaluate whether there is an independent association of impaired coronary flow and aortic elasticity in patients with MetS. Methods: Forty-six patients (mean age 47.3±6.6 years) with the diagnosis of MetS according to the ATP III update criteria and 44 age and gender matched controls (mean age 46.0±6.1 years) were included into the cross-sectional observational study. Peak diastolic coronary flow velocities were measured in left anterior descending artery by pulsed wave Doppler at baseline and after adenosine infusion, and CFR was calculated as the ratio of hyperemic to baseline velocities. Aortic strain, distensibility and stiffness were calculated by M-mode echocardiography. Statistical analysis was performed by using Student t-test, Chi-square test, Pearson correlation and linear regression analyses. Results: CFR was significantly lower in patients with MetS than in controls (2.3±0.2 vs 2.7 ±0.2, p<0.001). In the MetS group, aortic distensibility (10.4±3.5 cm2.dyn-1.10-6 vs 12.7±3.4 cm2.dyn-1.10-6, p=0.002) was decreased and AS was significantly increased (6.5±2.0 vs 3.2±0.8, p<0.001). In multivariate linear regression analysis, AS (β=-0.217, p=0.047), systolic blood pressure (β=-0.215, p=0.050) and waist circumference (β=-0.272, p=0.012) had an independent relationship with impaired CFR. Conclusion: This study demonstrated that coronary flow reserve is impaired in patients with MetS and there is an independent relationship between impaired CFR and increased aortic stiffness, systolic blood pressure or waist circumference.

PMID: 23395704  doi: 10.5152/akd.2013.070  Pages 237 - 242
Objective: There have been a large number of studies that have investigated the relationship between outcomes and provider volume for a wide variety of medical conditions and surgical conditions. The objective of this study was to explore the relation between hospital volume and risk-adjusted mortality following percutaneous coronary intervention between 2003 and 2004 in Korea. Methods: This is a retrospective analysis of database in National Health Insurance Review & Assessment Service and Korean National Statistical Office. The study data set confined to the ICD-10 diagnosis and procedure codes that were recorded in the National Health Insurance Review Agency. Risk modeling was performed through logistic regression and validated with cross-validation. The statistical performance of the developed model was evaluated using c-statistics, R2, and Hosmer-Lemeshow statistic. Crude and risk-adjusted 30-day mortality was evaluated among patients who underwent Percutaneous Coronary Intervention (PCI) between 2003 and 2004 at low (less 200 cases/year), medium (200~399 cases/year), and high (400 cases or more/year) PCI volume hospitals. Results: The final risk-adjustment model consisted of ten risk factors for 30-day mortality. These factors were found to have statistically significant effects on patient mortality. The c-statistic and Hosmer-Lemeshow χ2 goodness-of-fit test and the model’s performance were good [R2=0.147, c-statistic 0.823, 4.1037 (p=0.8476)]. A total number of 60 low-volume hospitals (9.071 patients) and 27 medium-volume hospitals (15.623 patients) and 15 high-volume hospitals (19.669 patients) were included. Crude 30-day mortality rate was 1.4%, 1.1%, and 1.0% (p=0.0106) in each volume hospitals. But risk-adjusted mortality rate was not significantly different among three groups (1.3%, 1.0%, and 1.1% in each volume hospitals). Conclusion: Although we found a significant different crude 30-day mortality rates according to hospital PCI volume, but did not find a relationship between hospital volume and 30-day risk-adjusted mortality rates following PCI in Korea.

PMID: 23261803  doi: 10.5152/akd.2013.050  Pages 245 - 250
Objective: There is conflicting data about the role of renin- angiotensin- aldosterone system (RAAS) blockers in contrast-induced nephropathy (CIN) pathophysiology. In this study, we aimed to investigate the effects of chronic usage of RAAS blocker drugs on development of CIN in low risk patients. Methods: Study was designed as a prospective cohort study. A total of 295 patients were enrolled in the study. Study population was consisted of three subgroups according to prior usage of RAAS blockers: no RAAS blocker group (n=95), angiotensin-converting enzyme inhibitor (ACEI) group (n=106), angiotensin receptor blocker (ARB) group (n=94). CIN was defined as an increase of ≥25% in creatinine over the baseline value or 0.5 mg/dL rise within 48-72 h of angiography. Mehran score was calculated for each patient. Baseline variables and percentage of CIN were compared with ANOVA, Mann-Whitney U, Kruskal-Wallis and Pearson Chi-square tests between groups. In order to determine the independent predictors of CIN, binary logistic regression analyses were performed. Results: CIN occurred in 18 patients (17.0%) in the ACEI group, 17 patients (18.1%) in ARB group and 7 patients (7.4%) in the no RAAS group. CIN occurrence was significantly higher in RAAS than no RAAS group (17.5% vs. 7.4%, p=0.01). Chronic RAAS blocker administration was an independent predictor of CIN (OR=2.69; 95% CI: 1.025-7.067; p=0.04). Mehran score was the only other independent predictor for CIN (OR=1.15; 95% CI: 1.019-1.310; p=0.02). Conclusion: In patients with near normal renal functions who are undergoing elective coronary procedure, chronic usage of ACEI and ARB increases the risk of CIN.

PMID: 23395706  doi: 10.5152/akd.2013.072  Pages 251 - 256
Objective: The aim of this study was to assess the right ventricular functions in patients with nasal polyposis using the strain (S) and strain rate (SR) echocardiography. Methods: A prospective, cross-sectional observational study was performed. The study included 40 patients with nasal polyposis (NP) (Group 1), and 25 healthy controls (Group 2). The study comprised patients with Stage 2 and Stage 3 nasal obstruction and no symptoms that could be associated with right ventricular heart failure. Longitudinal peak systolic strain (PSS) and peak systolic strain rate (PSSR) were measured from the basal-mid and apical segments of the right ventricle free wall. Student’s t-test, Pearson’s correlation analysis and Bland-Altman test were used for statistical analysis. Results: Pulmonary arterial systolic pressure was significantly higher in group 1 than group 2 (31.2±5.8, 19.7±4.3, respectively, p<0.001). PSS and PSSR values at the basal, mid and apical segments of the right ventricular lateral wall of the group I were significantly lower compared to the control group (p<0.001, p=0.002 and p=0.002 for PSS, p=0.003, p<0.001 and p<0.001 for PSSR, respectively). The comparison of Stage 2 and Stage 3 NP patients revealed a significant difference only in the SR measurement of the right ventricular mid segment (p=0.002). There was a significant correlation between the systolic pulmonary arterial pressure (sPAP) and right ventricular S and SR values (p<0.001). Conclusion: In this study, S/SR echocardiography showed a subclinical deficit of the right ventricular longitudinal functions in patients with NP who are considered to have normal right ventricular functions.

Visceral fat tissue is an important predictor of cardio-metabolic diseases, carrying more risk than general fat accumulation. Epicardial fat, a particular form of visceral fat deposited around the heart, is considered an important cardiovascular risk predictor, in view of producing and releasing several adipo-cytokines. There is growing evidence about the physiological and metabolic importance of epicardial fat. Epicardial fat thickness and volume have both strong correlation between obesity, impaired fasting glucose, insulin resistance, metabolic syndrome, hypertension, diabetes mellitus, and atherosclerosis. Epicardial fat can be assessed by transthoracic echocardiography, cardiac magnetic resonance imaging, and computed tomography. In this article, we reviewed the anatomy, physiology, function, and the methods of assessment of epicardial fat tissue. We also have tried to discuss its relationship to metabolic syndrome and coronary atherosclerosis in the lights of recent findings.

Heart failure is still an important public health problem despite important advances regarding its treatment. Several new treatment strategies are being investigated in order to contend with this disease. Strategies proved to be safe and effective in clinical trials are being adapted to clinical practice. In this review, we will first focus on most recent treatment strategies that are recommended to be used in clinical practice and then try to mention novel strategies which are still being explored in preclinical studies.
