The Relationship Between Controlling Nutritional Assessment Score and Mortality in Patients with Chronic Coronary Syndrome: A Retrospective Study from Türkiye.

BACKGROUND: Controlling Nutritional Assessment (CONUT) score has been shown to have a higher predictive value compared to other nutritional scores in acute coronary syndrome. AIM: To determine the relationship between CONUT score and long-term mortality in patients with chronic coronary syndrome (CCS). METHODS: Between 2017 and 2020, 585 consecutive patients newly diagnosed and proven to have CCS by coronary angiography were included in the study. CONUT score and demographic and laboratory data of all patients were evaluated. The relationship between results and mortality was evaluated. RESULTS: The mean age of the patients was 64 years and 75% were male. Mortality was observed in 56 (9.6%) patients after a median follow-up period of 3.5 years. The median CONUT score was significantly higher in patients with mortality (P < 0.001). In multivariate regression analysis, the CONUT score was associated with mortality (Hazard ratio (HR): 1.63 (95% confidence interval (CI): 1.34-1.98 P < 0.001)). The area under curve (AUC) for long-term mortality estimation for the CONUT score was 0.75 (95% CI 0.67-0.82 P < 0.001). When the CONUT score value was accepted as 0.5, the sensitivity was 78% and the specificity was 60. CONCLUSION: CONUT score was found to be predictive of mortality in long-term follow-up of patients with CCS.

Epicardial fat, body mass index, and triglyceride are independent contributors of serum fibroblast growth factor 21 level in obese premenopausal women.

PURPOSE: The hormone fibroblast growth factor 21 (FGF-21) regulates carbohydrate and lipid homeostasis. FGF-21 represents an attractive novel therapy for obesity since administration of FGF-21 has been shown to improve metabolic abnormalities in obese animal models. We investigated FGF-21 and its relationship with epicardial fat thickness (EFT), metabolic parameters, and inflammatory markers in premenopausal obese women compared to controls with similar Systematic Coronary Risk Evaluation (SCORE) project risk profiles. METHODS: Forty-five obese premenopausal women with body mass index (BMI) ≥30 kg/m(2) and 41 control premenopausal women with BMI <25 kg/m(2) with similar SCORE project risk profiles were included in this case-control study. EFT was evaluated by two-dimensional transthoracic echocardiography. Serum FGF-21 was measured with an ELISA kit. RESULTS: FGF-21 and EFT were significantly higher in obese women compared to controls (p < 0.001). Multiple stepwise linear regression analysis showed that EFT, BMI, and triglycerides (TG) independently contributed to FGF-21 (R(2) = 0.757, p < 0.001). However, homeostasis model assessment of insulin resistance (HOMA-IR), visceral ectopic fat, and inflammatory markers were not found as a direct contributor to serum FGF-21 level (p > 0.05). CONCLUSIONS: EFT, BMI, and TG may play an important role in predicting serum FGF-21 level which may be a potential therapeutic target in cardiometabolic disorders in the future.

The gap between the current dyslipidemia guidelines and the physicians' treatment targets in patients with type 2 diabetes in Turkey.

AIM: Lipid-lowering therapy (LLT) is a key factor in the prevention of cardiovascular mortality and morbidity in diabetic patients. Current guidelines have expanded the population of patients with diabetes for whom aggressive low-density lipoprotein cholesterol (LDL-C) lowering therapy should be considered. This study evaluated the management of dyslipidemia in patients with type 2 diabetes in real life. METHODS: Secondary care physicians in a tertiary center recruited 707 patients. The prevalence of statin use along with the achievement of cholesterol targets, predictors for receiving statin, and possible reasons for lack of therapy were investigated. RESULTS: Only 33% of the patients had received statin therapy, and this was significantly higher in those with cardiovascular disease (47% versus 27%; P<0.001). Most of the patients had LDL-C levels of >100 mg/dL (77%), with only 5% having LDL-C levels of <70 mg/dL. Forty-one percent of the patients had never been prescribed LLT previously while 26% had been prescribed this type of therapy in the past but had stopped using it. The most frequent reason for discontinuation of the statin therapy was a physician's advice to stop the medication. The patients taking statins had similar LDL-C levels as those who had never been prescribed statins and those who had discontinued their use of statins on the advice of a physician. CONCLUSION: The majority of diabetic patients are undertreated with statins and minority of them achieve LDL-C target levels. Our findings suggest that there is a large discrepency between evidence-based recommendations and physicians' treatment attitudes.

The effect of conversion type on P wave dispersion in patients with atrial fibrillation.

AIM: The aim of this study was to investigate whether conversion type of atrial fibrillation (AF) to sinus rhythm affects the P wave dispersion (PD) in patients with AF. METHODS: Based on conversion type, 95 consecutive patients with AF<3 months were divided into 3 groups: spontaneous cardioversion (SC) (N.=33, mean age: 60.6+/-11.6 years), pharmacologic cardioversion (PC) (N.=32, mean age: 59.2+/-9.6 years) and electrical cardioversion (EC) (N.= 30, mean age: 65.3+/-10.6 years). P wave duration (maximum and minimum) were measured in 12-lead ECG, and PD was calculated. RESULTS: Left atrial diameter and AF duration were significantly higher in EC (43.6+/-4.8 mm and 794.1+/-815.1 h) than SC (38.5+/-3.9 mm and 13.8+/-18.3 h) and PC (40.9+/-4.5 mm and 65.3+/-148.5 h) groups (P<0.01). P maximum was much longer in EC group compared with SC and PC group (121.6+/-9.7, 108.4+/-6.4 and 115.8+/-8.6 ms, P=0.01, respectively). There was a significant difference in PD among SC, PC and EC groups (44.4+/-9.2, 49.5+/-8.7 and 53.5+/-8.8 ms; P=0.005, respectively). PD correlated with AF duration (r=0.36, P=0.03), left atrial diameter (r=0.45, P=0.002) and conversion type (r=0.29, P=0.03). However, there was no significant association between PD and conversion type in multivariate analysis. The prolonged PD resulted from AF duration (P=0.01) and the left atrial size P=0.001). CONCLUSION: This study suggests that conversion type of AF to sinus rhythm has no effect on P wave duration and independent of AF duration and the left atrial diameter.

A unique case of anomalous coronary origin detected by 64-row multislice computed tomography coronary angiography.

The anomalous origin of the left coronary artery from the right sinus of valsalva is an anatomical abnormality that is usually associated with myocardial ischaemia and sudden death. We report on a case in which three different diagnostic techniques were used to find the cause of the ischaemic symptoms in a patient whose left coronary artery originated anomalously in the right sinus of valsalva and followed a course between the aorta and the pulmonary trunk. The techniques were treadmill exercise test for ischaemia, conventional angiography, which was used for the initial diagnosis, and 64-row multislice computerised tomography, used to determine the anomalous course of the artery.

Effect of levosimendan on right ventricular systolic and diastolic functions in patients with ischaemic heart failure.

OBJECTIVES: Levosimendan is a novel positive inotropic calcium sensitiser agent used in acute left heart failure. In this study, the effect of levosimendan on the right ventricular systolic and diastolic functions was evaluated by tissue Doppler comparing them with dobutamine in patients with ischaemic heart failure. METHODS: Patients having an acute decompensated heart failure with ischaemic cardiomyopathy and left ventricular ejection fraction <40% were included in the study. Before and 24-h after treatment, peak systolic (Sa), peak early (Ea), peak late (Aa) diastolic annular velocities and Ea/Aa ratio from tricuspid lateral annulus by tissue Doppler and systolic pulmonary artery pressure (SPAP) were measured. RESULTS: Sa, Ea and the Ea/Aa ratio were significantly increased in the levosimendan group whereas SPAP was significantly reduced. In the dobutamine group, no significant differences were observed in the Sa, Ea, Aa and Ea/Aa ratio in spite of a significant reduction in SPAP. Decrease in SPAP was greater in the levosimendan group (p=0.002). CONCLUSION: Levosimendan improves right ventricular systolic and diastolic functions.

Chylous ascites due to constrictive pericarditis.

Chylous ascites due to constrictive pericarditis is an extremely rare clinical entity, possibly caused by the augmented lymph production and high impedance to lymph drainage due to central venous hypertension. The authors describe a patient with chylous ascites caused by constrictive pericarditis in the absence of lymphatic obstruction. Cardiac catheterization is essential for the confirmation of accurate diagnosis of constrictive pericarditis. Magnetic resonance imaging of the heart is also very helpful in the diagnosis. The patient was symptom free and his ascites and edema completely resolved after pericardiectomy.

Must antidysrhythmic agents be given to all patients with new-onset atrial fibrillation?

We investigated the spontaneous conversion rate of new-onset atrial fibrillation (AF) in emergency department patients and the recurrence rate of AF during a 1 month follow-up period. Sixty-six consecutive hemodynamically stable patients presenting to a university hospital emergency department with new-onset atrial fibrillation (less than 72 hours duration) comprised the study population. Patients were initially monitored for 8 hours and observed for spontaneous conversion of AF to sinus rhythm. If conversion did not occur in the first 8 hours, an oral loading dose (600 mg) of propafenone was given, and patients were observed for an additional 8 hours. All patients were reevaluated at 24 hours and at 1 month. The spontaneous conversion rate in patients presenting within 6 hours of AF onset during the initial 8-hour observation period was 71%. The spontaneous conversion rate for all patients during the initial observation period was 53%. The conversion rates between patients presenting "early" (less than 6 hours) and "late" (7-72 hours) were significantly different (P < 0.001). Many patients with new-onset AF, especially those with atrial fibrillation duration less than 6 hours, may need observation only, rather than immediate intervention, to treat their dysrhythmia.

Catheter-induced vasospasm in the right external iliac and femoral arteries during a cardiac diagnostic procedure.

Catheter-induced vasospasm of small caliber arteries, such as the coronary arteries, is frequently observed during cardiac catheterization, but obstruction of the large caliber arteries has not previously been reported. Here we present two cases in which femoral and external iliac arteries were totally obstructed due to spasm during diagnostic coronary angiography.

Use of intraventricular dispersion of the peak diastolic flow velocity as a marker of left ventricular diastolic dysfunction in patients with atrial fibrillation.

The aim of this study was to evaluate the use of intraventricular dispersion of the peak diastolic flow velocity as a marker of left ventricular diastolic dysfunction in patients with atrial fibrillation. Regional diastolic flow velocity patterns at 1, 2, and 3 cm away from the mitral tip toward the apex were simultaneously recorded with the mitral flow velocity pattern by using pulsed Doppler echocardiography in 24 patients with atrial fibrillation before electrical or medical cardioversion. Echocardiographic examination was repeated after 10 to 30 days (ie, at the time of recovery of left atrial mechanical functions) after cardioversion of atrial fibrillation in all patients. Thirteen patients were found to have diastolic dysfunction; the remaining 11 patients with a normal E/A ratio constituted the control group. Afterward, the data recorded before the cardioversion were analyzed for each patient. In subjects with normal diastolic function, the peak diastolic flow velocity (PDFV) at the mitral tips also was maintained at the positions 1 to 3 cm away from the tip in the left ventricular cavity (PDFV at the mitral tips: 0.84 m/s, PDFV at 3 cm: 0.85 m/s; P =.34). In contrast, the regional PDFV progressively decreased toward the apex in patients with diastolic dysfunction (PDFV at the mitral tips: 0.82 m/s, PDFV at 3 cm: 0.63 m/s; P =.0004). Only 77% of the initial velocity was maintained at 3 cm away from the mitral tips in patients with diastolic dysfunction, whereas almost 100% of the initial velocity was preserved in patients with normal diastolic function (P <.001). These findings suggest that the assessment of the intraventricular decrease in mitral PDFV may be used as a reliable marker of diastolic dysfunction in patients with atrial fibrillation.

Predictors of success in the conversion of new-onset atrial fibrillation using oral propafenone.

We have investigated the relationship of clinical variables to successful cardioversion of atrial fibrillation (AF) to sinus rhythm using an oral loading dose of propafenone. Fifty consecutive patients with recent onset (< 72 hours) atrial fibrillation of various aetiologies were included in the study cohort. All patients were given the study medication while in the emergency department and then monitored for 8 hours. All patients converting to sinus rhythm (39 out of 50, 78%) were discharged and re-evaluated at 24 hours and 30 days. We investigated the effect of clinical factors such as age, sex, presence of hypertension (HT), chronic obstructive lung disease (COPD), diabetes mellitus (DM), mitral stenosis (MS), congestive heart failure (CHF), coronary artery disease (CAD) and the duration of atrial fibrillation on conversion to sinus rhythm. Of these factors, univariate and multivariate analysis showed that only the duration of atrial fibrillation was a significant predictor of conversion (p = 0.002). Our results suggest that most patients with new-onset AF can be converted successfully to sinus rhythm with a low incidence of adverse reactions using oral propafenone in the emergency department.

Correlation between serum lipoprotein(a) and angiographic coronary artery disease in non-insulin-dependent diabetes mellitus.

OBJECTIVES: To examine the impact of diabetic state on the concentrations of lipoprotein(a) [Lp(a)] in patients with non-insulin-dependent diabetes mellitus (NIDDM) and the correlation between angiographic coronary artery disease (CAD) and serum Lp(a) concentrations in NIDDM. DESIGN: In this cross-sectional study of 26 patients with NIDDM and 19 nondiabetic sex- and age-matched patients who underwent coronary angiography. CAD was assessed visually using coronary artery score (CAS), and plasma Lp(a) was measured by an enzyme-linked immunosorbent assay. SETTING: The study was performed in an internal medicine clinic at a university hospital. SUBJECTS: Twenty-six age- and sex-matched patients with NIDDM and 19 control patients without diabetes. RESULTS: There was no significant difference between the Lp(a) concentrations of patients with NIDDM and nondiabetic subjects (P > 0.05). When patients with NIDDM were stratified by absence or presence of CAD, patients with CAD had higher levels of Lp(a) (P < 0.05). However, there was no significant correlation between the concentrations of Lp(a) and CAS (P > 0.05). CONCLUSIONS: Diabetic state does not have any impact on Lp(a) concentrations. Lp(a) excess seems to be atherogenic in patients with NIDDM as shown in nondiabetic patients in previous studies. Although diabetic patients with CAD have higher Lp(a) concentrations than the diabetic patients without CAD, Lp(a) levels were not correlated with CAS.
