ABSTRACT

Left ventricular (LV) apical thrombus formation is a well described and clinically important complication of acute myocardial infarction (MI) with a substantial risk of thromboembolism. Alterations in the inflammatory status may contribute to this complication. The aim of this study was to evaluate the predictive role of the systemic immune-inflammation index (SII) in identifying high risk patients who will develop an apical thrombus formation during the acute phase of anterior transmural infarction. Consecutive 1753 patients (mean age: 61.5 ±â€…9.6 years; male: 63.8 %) with first acute anterior MI who underwent primary percutaneous coronary intervention were assessed. Patients were divided into 2 groups according to the presence of apical thrombus. SII was calculated using the following equation: neutrophil (N) × platelet (P) ÷ lymphocyte (L). LV apical thrombus was detected on transthoracic echocardiogram in 99 patients (5.6%). Patients with an apical thrombus had lower LV ejection fraction, prolonged time from symptoms to treatment, higher rate of post-percutaneous coronary intervention thrombolysis in myocardial infarction flow ≤1 and significantly higher mean high-sensitivity C-reactive protein, and SII values and lower lymphocyte than those without an apical thrombus. Admission SII level was found to be a significant predictor for early LV apical thrombus formation complicating a first-ever anterior MI. This simple calculated tool may be used to identify high-risk patients for LV thrombus and individualization of targeted therapy.

ABSTRACT

In patients with severe aortic stenosis, the data about the incidence of acquired thrombocytopenia according to the use of balloon-expandable or self-expandable valves are limited. We investigated the relationship between the post-transcatheter aortic valve replacement (TAVR) thrombocytopenia and the balloon-expandable or self-expandable valves. A total of 127 consecutive patients who underwent TAVR were retrospectively analyzed. Among the study population, 61 (48%) patients underwent TAVR with the balloon-expandable valve and the 66 (52%) patients with the self-expandable valve. Procedural success did not differ between the groups (P = .575). The access site complications and in-hospital mortality were the same across the groups (P = .225 and P = .466). However, paravalvular (PV) leaks were significantly higher in the self-expandable valve group (P = .007). Among all, 65 patients experienced thrombocytopenia, which was more frequent in the self-expandable valve group (63.6 vs 37.7%, P = .005). In multivariate analyses, admission platelet count, PV leak, and self-expandable valve deployment were the predictors of thrombocytopenia (P = .001, P = .002, and P = .021, respectively). The present study showed a higher incidence of acquired thrombocytopenia in the self-expandable valve group. Although the procedural success was similar between the groups, postprocedural PV leaks were more common in the self-expandable valve group.

ABSTRACT

AIM: To determine the association of monocyte count-to-high-density lipoprotein (HDL)-cholesterol ratio, a recently emerged inflammatory marker, with abdominal aortic aneurysm (AAA) size. PATIENTS & METHODS: A total of 120 asymptomatic AAA subjects (99 male, mean age: 67.1 ± 10.2 years) were enrolled into the study. All data were compared between patients with low and high admission monocyte/HDL ratio. Multivariate linear regression analysis was performed to study the relationship between different variables and AAA size. RESULTS: Compared to patients with below-median monocyte/HDL ratio, aneurysm diameter was significantly higher in above-median monocyte/HDL ratio group (54.3 ± 10.6 mm vs 62.0 ± 12.4 mm, p < 0.001, respectively). Hypertension, coronary artery disease, monocyte/HDL ratio and C-reactive protein were independently associated with AAA diameter. CONCLUSION: Monocyte/HDL ratio is independently associated with AAA size.

ABSTRACT

AIM: This study aims to assess the predictive role of the preprocedural circulating monocyte to high-density lipoprotein (HDL) cholesterol ratio (MHR) on the occurrence of stent restenosis (SR) in patients with stable and unstable angina pectoris undergoing successful bare-metal stenting (BMS). PATIENTS & METHODS: Between February 2008 and June 2014, a total of 831 patients with stable and unstable angina pectoris who underwent successful BMS were retrospectively analyzed. Demographic and clinical characteristics of the patients were recorded. Left ventricular ejection fraction and laboratory data were also noted. RESULTS: In the receiver operating characteristics curve analysis, MHR >14 had 71% sensitivity and 69% specificity in predicting SR. CONCLUSION: Our study results show that preprocedural MHR is an independent predictor of SR in this patient population.

ABSTRACT

Serum uric acid (UA) is independently associated with hypertension and blood pressure (BP) variability (BPV) is associated with cardiovascular events and mortality in hypertensive patients. The aim of the present study was to assess the association of serum UA with BPV in 300 untreated essential hypertension patients (mean age 57.3±13.6 years). BPV was quantified as the standard deviation (SD) of the 24-hour, daytime, and nighttime mean values obtained by using ambulatory BP monitoring. In correlation analysis, log UA values were found to be positively correlated with 24-hour systolic BPV and nighttime systolic and diastolic BPV (Pearson coefficients of 0.246, 0.280, and 0.353, respectively; P<.001 for all). In multivariate analysis, log UA had an independent association with 24-hour systolic BPV and nighttime systolic and diastolic BPV. This study show for the first time that increased serum UA is independently associated with BPV in untreated essential hypertension patients.

ABSTRACT

Cardiac hepatopathy has generally been used to describe any liver damage caused by cardiac disorders in the absence of other possible causes of liver damage. Although there is no consensus on the terminology used, cardiac hepatopathy can be examined as congestive hepatopathy (CH) and acute cardiogenic liver injury (ACLI). CH is caused by passive venous congestion of the liver that generally occurs in the setting of chronic cardiac conditions such as chronic HF, constrictive pericarditis, tricuspid regurgitation, or right-sided heart failure (HF) of any cause, and ACLI is most commonly associated with acute cardiocirculatory failure resulting from acute myocardial infarction, acute decompensated HF, or myocarditis. Histologically, CH is characterized by sinusoidal dilation, replacement of hepatocytes with red blood cells extravasating from the sinusoids, and necrosis/apoptosis of zone 3 of the Rappaport acinus, and it could progress to cirrhosis in advanced cases. In ACLI, however, massive necrosis of zone 3 is the main histological finding. Primary laboratory findings of CH are elevated serum cholestasis markers including bilirubin, alkaline phosphatase, and γ-glutamyl-transpeptidase levels, whereas those of ACLI are a striking elevation in transaminase and lactate dehydrogenase levels. Both CH and ACLI have a prognostic value for identifying cardiovascular events and mortality and have some special implications in the management of patients undergoing ventricular assist device implantation or cardiac transplantation. There is no specific treatment for CH or ACLI other than treatment of the underlying cardiac disorder.

ABSTRACT

We hypothesised that increased on-admission and follow-up mean platelet volume (MPV) levels would correlate with adverse outcomes in patients with infective endocarditis (IE). A total of 108 consecutive patients were grouped into two according to median MPV level (≤ 8.6 and > 8.6 fL). Patients with MPV level of > 8.6 fL had a significantly higher rate of end-stage renal disease, Staphylococcus aureus infection, higher CRP levels, embolic events and in-hospital mortality compared to patients with MPV levels ≤ 8.6 fL. In multivariable Cox regression analysis, previous history of IE, S. aureus infection, end-stage renal disease, depressed LVEF, early surgical intervention, vegetation size ≥ 10 mm, presence of perivalvular abscess, higher on-admission platelet count, CRP and MPV levels emerged as independent predictors of in-hospital unfavourable outcomes. Patients with embolic events and in-hospital mortality revealed an incremental trend for MPV levels compared to patients without any adverse events. Our study results suggest that both on-admission and follow-up MPV levels may be a simple and available biomarker for risk stratification of IE patients.

ABSTRACT

BACKGROUND: Increased circulating D-dimer levels have been correlated with adverse outcomes in various clinical conditions. To our knowledge, the association of on-admission D-dimer and in-hospital mortality in infective endocarditis (IE) has not been investigated. We hypothesized that increased on-admission D-dimer levels would correlate with adverse outcomes when prospectively studied in patients with IE. METHODS: In this prospective study, a total of 157 consecutive patients with the definite IE diagnosis met the inclusion criteria and underwent testing for on-admission D-dimer and CRP assays. The outcome measure was in-hospital death from any cause. RESULTS: In-hospital mortality occurred in 40 (26%) patients. Increased levels of plasma D-dimer (5.1 ± 1.7 vs 1.9 ± 0.8, p<0.001), CRP [45(13-98) vs 12(5-28), p<0.001] were found in dead patients compared with those survived. In addition to S. aureus infection, increased leukocyte count, end-stage renal disease, LVEF<50%, vegetation size of >10mm, perivalvular abscess, on-admission D-dimer (HR: 1.32; 95% CI: 1.24-1.40; p<0.001) and CRP (HR: 1.18; 95% CI: 1.09-1.36; p=0.001) levels were significantly associated with in-hospital mortality. Furthermore, the sensitivity and specificity of D-dimer ≥ 4.2mg/L in predicting in-hospital death in IE were 86% and 85%, respectively. Moreover, the sensitivity and specificity of CRP levels ≥ 13.6 mg/L were 72% and 69%, respectively. CONCLUSION: Our findings suggest that on-admission D-dimer level may be a simple, available and valuable biomarker that allows us to identify high-risk IE patients for in-hospital mortality. D-dimer ≥ 4.2mg/L, CRP ≥ 13.6 mg/L were independently associated with IE related in-hospital death.

ABSTRACT

OBJECTIVES: Increased epicardial adipose tissue (EAT) thickness is a risk factor for cardiovascular diseases. Previous studies have demonstrated that EAT thickness is increased in patients with hypertension compared with normotensive individuals. In the current study, we aimed to evaluate whether echocardiographically measured EAT thickness differs among patients with normotension, prehypertension, hypertension, and the relation between EAT thickness and blood pressure levels in prehypertensives. STUDY DESIGN: Patients with prehypertension (n=50) and hypertension (n=50) and normotensive healthy subjects (n=50) according to the American Hypertension Guidelines (Joint National Committee 7) were enrolled in the study. All participants underwent transthoracic echocardiographic examination. EAT thickness was measured from the parasternal long-axis view at end-systole. RESULTS: Compared with normotensives, EAT thickness was significantly increased in subjects with prehypertension and hypertension (4.1±1.1 mm, 5.4±1.3 mm and 6.6±1.5 mm, respectively, p<0.001). After adjustment for confounding factors like age, gender, high-density lipoprotein, waist circumference, and body mass index, EAT thickness in the normotensive, prehypertensive and hypertensive groups was measured as 4.3±1.2 mm, 5.3±1.2 mm and 6.4±1.4 mm, respectively (p=0.001). In the prehypertensive group, multivariable linear regression analysis showed that EAT thickness was positively correlated with both systolic (r=0.305, p=0.001) and diastolic (r=0.297, p=0.001) blood pressures, independent of other risk factors. CONCLUSION: In addition to hypertensive subjects, echocardiographically measured EAT thickness is increased in prehypertensive patients when compared with normotensive subjects, independent of other factors. Additionally, increased EAT thickness is significantly correlated with systolic and diastolic blood pressure levels in patients with prehypertension.

ABSTRACT

BACKGROUND: Fragmented QRS complex (fQRS) is associated with cardiovascular outcomes in various patient populations. Although there were clinical studies investigating the association of fQRS with arrhythmic events in patients with systolic heart failure, the results were conflicting regarding the association of implantable cardioverter defibrillator (ICD) shocks and fQRS. In this study, we aimed to evaluate the association between the presence and extent of fQRS with appropriate ICD shocks and/or all-cause mortality. METHODS: A total of 215 patients (age: 58.2 ± 11.6 years, 72.5 % male) with the diagnosis of left ventricular systolic heart failure in whom ICD had been implanted for primary prophylaxis were enrolled. Standard ECG evaluation revealed fQRS complex in 123 patients (57.2 %). The phenomenon of fQRS was defined as deflections at the beginning of the QRS complex, on top of the R wave, or in the nadir of the S wave similar to the definition in CAD. RESULTS: At mean 23.5 ± 12.1 months follow-up, all-cause mortality was observed in 45 (20.9 %) patients and 111 (51.6 %) patients experienced appropriate ICD shocks. Median number of ECG leads with fQRS were higher in patients with appropriate ICD shocks (3 [2-6] vs 1 [0-2], P < 0.001, respectively). The presence of fQRS (HR: 6.64, 95 % CI: 3.54-12.4, P < 0.001) and the number of leads with fQRS (HR: 1.35, 95% CI: 1.22-1.67) were found as independent predictors of appropriate ICD shocks. Additionally, there was a negative correlation between left ventricular ejection fraction and the number of leads with fQRS (r = -0.434, P < 0.001). Rates of all-cause mortality did not differ between the fQRS(+) (29 [24 % ]) and fQRS(-) (16 [17 % ]) groups (P = 0.27). CONCLUSION: Our findings suggest that the presence and extent of fQRS complex on standard 12-lead ECG predicts appropriate ICD shocks in patients with left ventricular systolic heart failure who underwent ICD implantation for primary prophylaxis.

ABSTRACT

BACKGROUND: Fragmented QRS complex (fQRS) is associated with worse outcomes in several cardiovascular conditions. However, alterations in fQRS in patients with ST elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) and association of fQRS with myocardial blush grade (MBG) has not been investigated until now. In this study, we aimed to investigate the association of MBG after primary PCI with evolution of fQRS. METHODS: Our study consisted of 401 consecutive patients with STEMI who underwent primary PCI. Patients were categorized into two subgroups according to persistence or new-onset of fQRS (Group 1) and absence or resolution of fQRS (Group 2) at 48 hours after primary PCI. The evolution of fQRS on pre- and post-PCI ECG and their relation with myocardial reperfusion parameters were investigated. RESULTS: Patients in group 1 showed older age, higher rate of smoking, lower HDL-cholesterol, lower LVEF, higher angina-to-door time, higher TIMI frame count, and high rate of patients with MBG <3 compared to patients with group 2 (P < 0.05). In correlation analysis, LVEF showed positive correlation with MBG (r = 0.448, P < 0.001) and negative correlation with the number of leads with fQRS (r = -0.335, P < 0.001). In multivariate regression analysis, new-onset or persistance of fQRS after primary PCI is significantly associated with MBG <3, peak CK-MB level, pre-PCI fQRS at anterior localization and smoking. CONCLUSION: Our findings showed that despite complete ST-segment resolution in all patients, fQRS is independently associated with impaired microvascular myocardial perfusion. So, fQRS, as a simple and easily available noninvasive marker, may be useful in stratification of high-risk patients with increased extent of infarcted myocardium who underwent primary PCI.

ABSTRACT

Angiosarcoma, the most common primary malignant neoplasm of the heart in adults, usually presents as pericardial effusion or right-sided heart failure. Rupture of an angiosarcoma-infiltrated cardiac chamber as a cause of hemothorax is very rare in the literature. In this report, we describe a 34-year-old male patient, who presented to emergency service with sudden chest pain and dyspnea. The diagnostic work-up revealed spontaneous right-sided hemothorax and a large right atrial (RA) mass with suspicious atrial perforation. An urgent surgery showed a vascularized irregular RA mass invading the parietal pericardium and pleura and a perforation of the RA free wall. Histopathologic examination confirmed the diagnosis of angiosarcoma, and the patient was subsequently referred for radiotherapy and chemotherapy.

ABSTRACT

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 (ß=-0.217, p=0.047), systolic blood pressure (ß=-0.215, p=0.050) and waist circumference (ß=-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.

ABSTRACT

Uric acid (UA) is independently associated with the emergence of hypertension. Nocturnal nondipping pattern of hypertension is associated with a greater risk of cardiovascular, renal, and cerebrovascular complications than dippers. The aim of the present study was to evaluate the relationship between the circadian blood pressure rhythm and UA level in patients with newly diagnosed essential hypertension. The study included 112 essential hypertensive patients and 50 healthy controls. The hypertensive patients were divided into two groups according to the results of 24-hour ambulatory blood pressure monitoring, including 60 dippers (35 men, 25 women; mean age, 52.6±15.8 years) and 52 nondippers (29 men, 23 women; mean age, 55.9±13.2 years). Nondippers had significantly higher serum UA levels than the dippers and controls (5.8±0.8, 5.1±0.9 and 4.2±0.9 mg/dL, respectively; P<.001). Serum high-sensitivity C-reactive protein levels were also significantly higher in the nondipper group than the other groups (P<.001) and significantly correlated with serum UA (r=0.358, P<.001). Multivariate logistic regression analysis revealed an independent positive association between serum UA levels and nondipper pattern (odds ratio, 2.28; 95% confidence interval, 1.33-3.94; P=.003). Serum UA is strongly and independently associated with the nondipper circadian pattern in essential hypertension.

ABSTRACT

OBJECTIVES: 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. Epicardial fat thickness (EFT) reflects visceral adiposity and is considered an important cardiometabolic marker. In this study, we aimed to examine the presence of an association between CFR and EFT in MetS patients. METHODS: Forty-six MetS patients (25 men, mean age 47.3±6.6 years) and 44 age-matched and sex-matched controls (24 men, mean age 46.0±6.1 years) were prospectively studied. Both CFR and EFT were measured by transthoracic echocardiography. Peak diastolic coronary flow velocities were measured in the left anterior descending artery by pulsed wave Doppler at the baseline and after adenosine infusion, and CFR was calculated as the ratio of hyperemic to baseline velocities. RESULTS: The waist circumference, total and low-density lipoprotein-cholesterol, fasting glucose, triglycerides, systolic and diastolic blood pressures, and high sensitive C-reactive protein were significantly higher in MetS patients. The mean EFT was significantly higher in MetS patients compared with the controls (8.7±0.2 vs. 4.8±0.1 mm, P<0.001); however, CFR was significantly lower in MetS patients (2.3±0.2 vs. 2.7±0.2, P<0.001). CFR was correlated significantly with BMI, waist circumference, high-density lipoprotein-cholesterol, triglycerides, fasting glucose, high sensitive C-reactive protein, and EFT. In regression analysis, MetS itself and EFT were found to be independent predictors of impaired CFR. CONCLUSION: CFR is impaired in MetS patients. MetS itself and increased EFT are associated independently with coronary microvascular dysfunction and EFT is a predictor of worse CFR even after accounting for the presence or absence of the MetS.
