Impact of right ventricular diastolic dysfunction on clinical outcomes in inferior STEMI.

BACKGROUND: The aim of this study was to investigate the prognostic value of restrictive right ventricular filling pattern (RRVFP) in patients with the first acute inferior wall myocardial infarction (IWMI) complicated by right ventricular myocardial infarction (RVMI) undergoing primary percutaneous coronary intervention (p-PCI). METHOD: A total of 152 patients with acute IWMI complicated by RVMI undergoing p­PCI were divided into two groups according to the presence of RRVFP. RRVFP was defined as tricuspid diastolic early/late flow velocities (Et/At) > 2 and Et deceleration time (DT) < 120 ms. RESULTS: There were 23 patients with RRVFP in the study cohort. At, DTt, isovolumetric relaxation time (IVRT), and tissue Doppler tricuspid annular late velocity (A't) were reduced significantly in patients with RRVFP than in those without RRVFP (At 19.6 ± 2.7 vs. 39.1 ± 7.4 cm/s, p < 0.001; DTt 106 ± 13 vs.156 ± 21 ms, p = 0.001; IVRT 59 ± 6.7 vs. 62 ± 7.4 ms, p = 0.01; A't 4.6 ± 1.1 vs. 8.6 ± 1.05, p = 0.001). Et/At ratios were higher in patients with RRVFP than in those without RRVFP (Et/At 2.20 ± 0.2 vs. 1.15 ± 0.37, p < 0.001). Et, tissue Doppler tricuspid annular early velocity (E't), E't/A't ratio, and Et/E't ratio were not significantly different between groups (Et 43.3 ± 5.4 vs. 40.7 ± 9.2 cm/s p = 0.18; E't 8.8 ± 1.4 vs. 9.5 ± 2.3, p = 0.15; E't/A't 1.08 ± 0.24 vs. 1.13 ± 0.30, p = 0.52; Et/E't ratio 5.0 ± 1.1 vs. 4.5 ± 1.5 p = 0.09). Presence of E't/A't > 2, short DTt, RRVFP, unsuccessful p­PCI, and cardiogenic shock on admission were independent predictors of in-hospital mortality (p < 0.05) in multivariable logistic regression analysis. CONCLUSION: Presence of RRVFP is associated with in-hospital mortality in patients presenting with their first IWMI complicated by RVMI.

The novel diagnostic marker in low-LVEF heart failure patients.

OBJECTIVE: The structural and compositional changes in the myocardium seem to have a major role in the development of heart failure (HF).Imbalance between production and degradation in extracellular collagen results in increase of collagen synthesis biomarkers in the circulation as the carboxy-terminal propeptide of type I procollagen (PIP). Here we aimed to determine role of PIP in the diagnosis of chronic HF. MATERIAL AND METHODS: 87 patients with HF group and 80 healthy subjects were enrolled into the study. Echocardiographic examination was performed.At the beginning of the study, serum B type natriuretic peptide (BNP), PIP, high sensitive C-reactive protein (hs-CRP) were measured . The subjects were followed for one year then after. RESULTS: Average PIP value of HF group was significantly higher than that of the control group (p < 0.001). Both hs-CRP and BNP values were well correlated to PIP values (p < 0.001). In the HF group, PIP value of patients who died at the end of one year was similar to that of patients who survived at the end of first year. CONCLUSION: PIP may not mirror acute events in follow-up of chronic heart failure but it is a very beneficial biomarker in diagnosis of low-LVEF heart failure with high sensitivity and specificity (Tab. 2, Fig. 1, Ref. 16).

Risk of hypertension in Yozgat Province, Central Anatolia: application of Framingham Hypertension Prediction Risk Score.

The aim of this cross-sectional study was to estimate the risk of hypertension in 1106 Caucasian individuals aged 20-69 years in Yozgat Province, using the Framingham Hypertension Risk Prediction Score (FHRPS). According to FHRPS, average risk of developing hypertension over 4 years was 6.2%. The participants were classified into low- (<5%), moderate- (5% to 10%) and high- (>10%) risk groups. The percentage of participants that fell into these groups was 59.4%, 19.8% and 20.8% respectively. The proportion of participants in the high-risk group was similar to the 4-year incidence of hypertension (21.3%) in the Turkish population. Regression analysis showed that high salt consumption and low educational level significantly increased the risk of hypertension. Economic level, fat consumption, life satisfaction, physical activity, and fruit and vegetable consumption were not correlated with risk of hypertension. This study shows that FHRPS can also be used for predicting risk of hypertension in Central Anatolia.

Long term follow-up of four patients with Keutel syndrome.

Keutel syndrome (KS) [OMIM 245150] is an autosomal recessive hereditary syndrome characterized by multiple peripheral pulmonary stenoses (PPS), brachytelephalangia, inner ear deafness, and abnormal cartilage ossification or calcification. Mutations in the matrix Gla protein (MGP) gene have been reported in different unrelated families with KS previously. MGP is an extracellular matrix protein and calcification inhibitor; mutations in its encoding gene result in cartilage ossification or calcification, the main presenting feature of KS. This report describes the findings of four sisters with KS born to consanguineous parents were followed for 26 years in an irregular fashion. During follow-up of the patients over the years the complications appear to be mostly involving the respiratory system. Permanent skin rashes, papillary microcarcinoma of the thyroid, asthma, massive bullous pulmonary emphysema, severe systemic arterial hypertension, and short term memory loss were observed during long term follow-up. The fertility status of the patients were also observed and infertility was observed in one of three married patients.

Coronary rupture and pseudoaneurysm formation after extravascular migration of a paclitaxel eluting stent implanted in the left circumflex coronary artery.

As the implantation of drug eluting stents (DES) has become one of the most common clinical practices in interventional cardiology, the complications secondary to this procedure appear to have emerged increasingly over the past decade, with many cases of development of new coronary artery true aneurysms after DES implantation being reported. Here we present a case of coil embolization of a coronary pseudoaneurysm which presumably formed after extravascular migration of a DES.

The importance of the incidental thyroid gland uptake during Tc-99m MIBI myocardial perfusion scintigraphy.

OBJECTIVE: The purpose of study was to investigate whether incidental thyroid gland uptake had an important during Tc-99m sestamibi (MIBI) myocardial perfusion scintigraphy (SPECT). PATIENTS AND METHODS: In the presented study, 968 consecutive patients were evaluated for the presence or absence of thyroid gland uptake in the raw data of the Tc-99m MIBI SPECT. All of the patients had thyroid gland uptake of the Tc-99m MIBI underwent laboratory evaluation of thyroid function, ultrasonographic imaging, and hystopathological examination. RESULTS: The thyroid gland uptake was detected in 14 of 968 (1.4%) consecutive patients during the evaluation of raw images of Tc-99m MIBI SPECT studies. Among these 14 patients, 4 had subacute thyroiditis, 7 multinodular goiter, 3 Graves disease by ultrasonographic imaging and hystopathological examination. TSH levels of all of these patients were < 0.01 U/ml. CONCLUSIONS: Tc-99m MIBI uptake by thyroid gland has been explained with associated clinical thyrotoxicosis. Although the primary goal of myocardial perfusion imaging is the evaluation of myocardial perfusion, the interpretation of myocardial perfusion imaging should not be limited to the heart. Because, it is possible to observe extracardiac radioactivity accumulation, which may then lead to the diagnosis of a noncardiac disease during this detailed examination.
