Effect of the number of parity on right heart chamber quantification.

INTRODUCTION: Pregnancy is a process that can cause several physiologic changes to the cardiovascular system such as ventricular hypertrophy and dilation of cardiac chambers. Although there are studies about pregnancy-related changes in echocardiographic examination; there is no data about the long-term effects of parity on these alterations. Therefore, we evaluated the long-term effect of pregnancy on right ventricular (RV) dilation and RV hypertrophy and their relation to the parity number. METHODS: This prospective study included a total of 600 women (200 consecutive women who had no parity, 200 women who had a parity number of 1 to 4 and 200 women who had a parity number of more than 4). Right chambers' measurements were compared between the groups. RESULTS: In echocardiographic analysis, RV and right atrial dimensions and areas and RV wall thickness were higher in parous women. On the other hand, RV systolic function parameters were significantly lower in parous women. These significant changes showed a gradual increase or decrease by increasing parity number. By multivariate hierarchical logistic regression analysis, the four independent factors that increased the risk of RV dilation were age (OR: 1.16 CI: 1.10-1.20), body mass index (OR: 1.05, CI: 1.02-1.08), smoking (OR: 1.87, CI: 1.28-4.02), and giving a birth (OR: 3.94 CI: 1.82-8.81). There was also independent relationship between the number of parity and RV hypertrophy even after adjustment for several confounders. CONCLUSION: Pregnancy-related physiological changes mostly resolve after delivery. This study about long-term effects of pregnancy on RV has demonstrated that there is a significant relation between the number of parity and either RV dilation or RV hypertrophy. Each parity had also additive effect on these changes.

Balloon Angioplasty Versus Stenting in Patients With ST-Elevated Myocardial Infarction Before Subsequent Coronary Artery By-Pass Grafting.

Decision of ad hoc revascularization strategy in patients who require coronary artery bypass grafting (CABG) following primary percutaneous coronary interventions (PCI) is challenging due to the pros and cons of only-ballooning and stenting. In this study, we aimed to compare the outcomes of only-balloon-angioplasty to stenting in primary PCI in patients with ST elevated myocardial infarction (STEMI) who required a subsequent CABG. We retrospectively analyzed 350 consecutive STEMI patients who needed CABG in addition to primary balloon angioplasty (n = 160) and stenting strategy (n = 190). In-hospital and 5-year outcomes of the patients were compared between the 2 groups. In-hospital mortality rates in the ballooning and stenting groups were not nonsignificantly different (11.2% vs 9.5%, respectively, P = .59); 5-year mortality rates were also similar between the 2 groups (9.2% vs 8.7%, P = .89). Additionally, major bleeding rates (3.8% vs 6.3%, P = .28) did not differ between the 2 groups. In conclusion, our study showed no significant difference in-hospital and long-term mortality rates in patients who require CABG after primary PCI irrespective of the ad hoc revascularization strategy.

Acute myocardial infarction associated with clomiphene citrate in a young woman.

Clomiphene citrate is a drug that stimulates ovulation and is commonly used in cases of female infertility. Generally, it is recognized as a safe agent for ovulation induction, but rarely, it is associated with life-threatening conditions. A 36-year-old woman who had been prescribed clomiphene citrate for infertility was admitted to the emergency department for chest pain lasting for 2 hours. She had no history of smoking, and she did not have any cardiac risk factor for myocardial infarction (MI). An electrocardiogram performed on admission revealed ST-elevation in the precordial leads. She was taken to the catheter laboratory for ST-elevation myocardial infarction, and the coronary angiography revealed total occlusion of the midportion of the left anterior descending artery (LAD) with a heavy thrombus burden. The circumflex and right coronary arteries were normal. After balloon dilatation, a 2.75x15-mm drug eluting stent was implanted in the mid part of the LAD. The patient had an uncomplicated recovery. Before discharge, echocardiography revealed apical akinesis; anterior and lateral hypokinesis; and an ejection fraction of 45% with mild mitral regurgitation. Although clomiphene citrate is a relatively safe drug for ovarian stimulation, it has been associated with serious side effects, such as MI. Physicians should be aware of the potential risks of clomiphene citrate, especially in patients with risk factors for coronary artery disease.

Iron deficiency and hematinic deficiencies in atrial fibrillation: A new insight into comorbidities.

OBJECTIVE: Iron deficiency (ID) is the most common nutritional deficiency, and iron metabolism becomes further deteriorated in the presence of certain conditions, such as heart failure (HF). Atrial fibrillation (AF) has many similarities to HF, including a chronic inflammatory pathophysiology; however, the prevalence of ID and other hematinic deficiencies in AF patients have not been determined. METHODS: In this study, the prevalence of iron (serum ferritin <100 µg/L or ferritin 100-299 µg/L with transferrin saturation <20%), vitamin B12 (<200 pg/mL), and folate deficiency (<4.0 ng/mL) was evaluated in 101 patients with non-valvular AF with preserved left ventricular ejection fraction and no signs of HF, and the results were compared with 35 age- and gender-matched controls. RESULTS: Anemia was detected in 26% of the patients. A total of 48 (47.6%) patients had ID, 10 (9.9%) had a vitamin B12 deficiency, and 13 (12.9%) had a folate deficiency. The prevalence of ID was similar in the controls and the paroxysmal AF patients, but increased gradually in persistent and permanent AF. Univariate logistic regression analysis demonstrated that permanent vs. paroxysmal AF [Odds ratio (OR): 2.17; 95% confidence interval (CI): 0.82-5.69; p=0.011], high sensitive C-reactive protein (OR: 1.47; 95% CI: 0.93-2.36; p=0.019), N-terminal pro b-type natriuretic peptide (OR: 1.24; 95% CI: 0.96-1.71; p=0.034), and white blood cell count (OR: 1.21; 95% CI: 0.95-1.58; p=0.041) were associated with ID. In multivariable analysis, permanent AF remained as an independent clinical associate of ID (OR: 4.30; 95% CI: 0.83-12.07; p=0.039). CONCLUSION: ID is common in permanent AF, as in HF. Inflammation and neurohormonal activation seem to contribute to its development.

Effect of nutritional status on mortality in patients undergoing coronary artery bypass grafting.

OBJECTIVES: The prognostic effects of poor nutritional status and cardiac cachexia on coronary artery disease (CAD) are not clearly understood. A well-accepted nutritional status parameter, the prognostic nutritional index (PNI), which was first demonstrated to be valuable in patients with cancer and those undergoing gastrointestinal surgery, was introduced to patients requiring coronary artery bypass grafting (CABG). The aim of the present study was to evaluate the prognostic value of PNI in patients with CAD undergoing CABG. METHODS: We evaluated the in-hospital and long-term (3-y) prognostic effect of PNI on 644 patients with CAD undergoing CABG. Baseline characteristics and outcomes were compared among the patients by PNI and categorized accordingly: Q1, Q2, Q3, and Q4. RESULTS: Patients with lower PNI had significantly higher in-hospital and long-term mortality. Patients with lower PNI levels (Q1) had higher in-hospital mortality and had 12 times higher mortality rates than those with higher PNI levels (Q4). The higher PNI group had the lower rates and was used as the reference. Long-term mortality was higher in patients with lower PNI (Q1)-4.9 times higher than in the higher PNI group (Q4). In-hospital and long-term mortality rates were similar in the non-lower PNI groups (Q2-4). CONCLUSION: The present study demonstrated that PNI, calculated based on serum albumin level and lymphocyte count, is an independent prognostic factor for mortality in patients undergoing CABG.

The prognostic significance of early and late right precordial lead (V4 R) ST-segment elevation in patients with acute anterior myocardial infarction.

BACKGROUND: The predictive significance of ST-segment elevation (STE) in lead V4 R in patients with anterior ST-segment elevation myocardial infarction (STEMI) has not been well-understood. In this study, we evaluated the prognostic value of early and late STE in lead V4 R in patients with anterior STEMI. METHODS: A total 451 patients with anterior STEMI who treated with primary percutaneous coronary intervention (PPCI) were prospectively enrolled in this study. All patients were classified according to presence of STE (>1 mm) in lead V4 R at admission and/or 60 min after PPCI. Based on this classification, all patients were divided into three subgroups as no V4 R STE (Group 1), early but not late V4 R STE (Group 2) and late V4 R STE (Group 3). RESULTS: In-hospital mortality had higher rates at group 2 and 3 and that had 2.1 and 4.1-times higher mortality than group 1. Late V4 R STE remained as an independent risk factor for cardiogenic shock (odds ratio [OR] 2.6; 95% confidence interval [CI] 1.9-4.3; p < .001) and in-hospital mortality (OR 2.3; 95% CI 1.8-4.1; p < .001). The 12-month overall survival for group 1, 2, and 3 were 91.1%, 82.4%, and 71.4% respectively. However, the long-term mortality also had the higher rate at group 3; late V4 R STE did not remain as an independent risk factor for long-term mortality (OR 1.5; 95% CI 0.8-4.1; p: .159). CONCLUSION: Late V4 R STE in patients with anterior STEMI is strongly associated with poor prognosis. The record of late V4 R in patients with anterior STEMI has an important prognostic value.

ST Depression, No ST Change, or ST Elevation in Inferior Derivations: Which Has the Worst Outcomes in Acute Anterior Myocardial Infarction?

OBJECTIVE: The combination of electrical phenomena and remote myocardial ischemia is the pathophysiological mechanism of ST segment changes in inferior leads in acute anterior myocardial infarction (MI). We investigated the prognostic value of ST segment changes in inferior derivations in patients with first acute anterior MI treated with primary percutaneous coronary intervention (PCI). METHODS: In this prospective single-center analysis, we evaluated the prognostic impact of ST segment changes in inferior derivations on 354 patients with acute anterior MI. Patients were divided into the following 3 groups according to admission ST segment changes in inferior derivations: ST depression (group 1), no ST change (group 2), and ST elevation (group 3). RESULTS: In-hospital multivariate analysis revealed notably high rates of in-hospital death for patients in group 3 compared to patients in group 2 (OR 2.5; 95% CI 1.6-7.6, p < 0.001). Group 1 and group 2 had similar in-hospital and long-term mortality rates. After adjusting for confounding baseline variables, group 3 had higher rates of 18-month mortality (HR 3.3; 95% CI 1.5-8.2, p < 0.001). CONCLUSION: In patients with a first acute anterior MI treated with primary PCI, ST elevation in inferior leads had significantly worse short-term and long-term outcomes compared to no ST change or ST segment depression.

Which admission electrocardiographic parameter is more powerful predictor of no-reflow in patients with acute anterior myocardial infarction who underwent primary percutaneous intervention?

BACKGROUND: Acute transmural ischemia due to left anterior descending artery (LAD) occlusion changes precordial R and Q wave durations owing to depressed intramyocardial activation. We investigated the prognostic value of sum of precordial Q wave duration/sum of precordial R wave duration ratio (Q/R) in patients with first acute anterior myocardial infarction (AAMI) treated with primary percutaneous coronary intervention (PPCI). METHODS: In this prospective analysis, we evaluated the no-reflow predictive value of Q/R on 403 patients with first AAMI. Patients were divided into two as no-reflow group (n=32) and control (n=371) group according to post-PPCI flow status. RESULTS: The patients in the no-reflow group had significantly higher Q/R on admission electrocardiography (ECG) compared to patients in the control group (p<0.001). When admission ECG parameters were compared according to no-reflow prediction, Q/R was stronger than other well-accepted parameters. The best cut-off value of the Q/R to predict no-reflow was 1.08 with 76% sensitivity and 73% specificity (AUC: 0.78; 95% CI: 0.72-0.83; p<0.001). CONCLUSION: In patients with first AAMI treated with PPCI, Q/R in admission ECG may have a role as an independent predictive marker of no-reflow.

A simple independent prognostic electrocardiography parameter in first acute anterior myocardial infarction; Precordial total Q wave/precordial total R wave.

BACKGROUND: We investigated the prognostic value of precordial total Q wave amplitude/precordial total R wave amplitude ratio (Q/R) in patients with first acute anterior MI treated with primary percutaneous coronary intervention (PPCI). METHODS: We evaluated the in-hospital prognostic impact of Q/R on 354 patients with first acute anterior MI. Patients were stratified by tertiles of admission Q/R, clinical outcomes were compared between those groups. RESULTS: In-hospital univariate analysis revealed notably higher rates of in-hospital death for patients in tertile 3, as compared to patients in tertile 1 (OR 9.7, 95% CI 2.8-33.5, p. CONCLUSION: Q/R in admission ECG in patients with first acute anterior MI provide an independent prognostic marker of in-hospital outcomes.

Effect of Adjunctive Thrombus Aspiration on In-Hospital and 3-Year Outcomes in Patients With ST-Segment Elevation Myocardial Infarction and Large Native Coronary Artery Thrombus Burden.

Although the long-term clinical benefit of adjunctive thrombus aspiration (TA) during primary percutaneous coronary intervention (PPCI) remains controversial, the impact of TA in patients with large thrombus has not been evaluated. The aim of the present study was to investigate the effect of adjunctive TA during PPCI on clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) and a large thrombus. We assessed the effect of adjunctive TA on in-hospital and 3-year clinical outcomes in 627 patients with STEMI and a large thrombus in the native coronary artery. The cumulative 3-year incidence of all-cause death was not significantly different between the 2 groups (91.5% vs 89.0%, log-rank test p = 0.347). After adjusting for confounders, the risk of all-cause death in the TA group was not significantly lower than that in the non-TA group (hazard ratio 1.11, 95% confidence interval 0.60 to 3.54, p = 0.674). The adjusted risks of target lesion revascularization, nonfatal acute myocardial infarction, and stent thrombosis were also not significantly different between the 2 groups. In conclusion, adjunctive TA during PPCI was not associated with better in-hospital and 3-year all-cause deaths in patients with STEMI and a large coronary artery thrombus.

Relation of the Number of Parity to Left Ventricular Diastolic Function in Pregnancy.

Left ventricular diastolic dysfunction (LVDD) has been relatively less studied than other cardiac changes during pregnancy. Previous studies revealed a mild diastolic deterioration during pregnancy. However, these studies did not evaluate the long-term effect of parity on left ventricular diastolic function. A comprehensive study evaluating the long-term effect of parity on diastolic function is required. A total of 710 women with various number of parity were evaluated through echocardiography to reveal the status of diastolic function. Echocardiographic parameters were compared among the women by parity number and categorized accordingly: none, 0 to 4 and 4< parity (grand multiparous). In nulliparous group, 19 women (23.2%) had grade 1 LVDD, and only 2 women (2.4%) had grade 2 LVDD. In women with a parity number of 0 to 4, 209 women (38.3%) had grade 1 LVDD, and only 17 women (3.1%) had grade 2 LVDD. In grand multiparous group, only 2 women (2.4%) did not have LVDD, and 12 women (14.6%) had grade 2 LVDD. None of the subjects had grade 3 or grade 4 LVDD. According to hierarchical logistic regression analysis, any grade of LVDD and grade 2 LVDD had the highest rates at parity category of > 4 parity and that had 21 and 5.8 times higher than nulliparous group, respectively. In conclusion, according to the present study, grand multiparity but not multiparity, severely deteriorates left ventricular diastolic function. Further studies are warranted to evaluate the risk of gradual diastolic dysfunction after each pregnancy.

An unexpected complication of acute pancreatitis: Intra-cardiac thrombus.

Left atrial thrombus after acute pancreatitis (AP) is a rare clinical statement. Because of induction of systemic prothrombotic process by AP; some patients with underlying risk factors may develop an intra-cardiac thrombus. We present a 53years-old-woman with moderate mitral stenosis and atrial fibrillation. However the patient was under warfarin treatment, she developed a big left atrial big thrombus which was originated from left atrial appendage after she was suffered from AP.

The effect of serum potassium level on in-hospital and long-term mortality in ST elevation myocardial infarction.

Current studies evaluating the effect of serum potassium levels on mortality in patients with ST elevation myocardial infarction (STEMI) are lacking. We analyzed retrospectively 3760 patients diagnosed with STEMI. Mean serum potassium levels were categorized accordingly: <3.0, 3.0 to <3.5, 3.5 to <4.0, 4.0 to <4.5, 4.5 to <5.0, 5.0 to <5.5, and ≥5.5mEq/L. The lowest mortality was determined in patients with serum potassium level of 4 to <4.5mEq/L whereas mortality was higher in patients with serum potassium levels of ≥5.0 and <3.5mEq/L. In a multivariable Cox-proportional regression analysis, the mortality risk was higher for patients with serum potassium levels of ≥5mEq/L [hazard ratio (HR), 2.11; 95% confidence interval (CI) 1.23-4.74 and HR, 4.20; 95% CI 1.08-8.23, for patients with potassium levels of 5 to <5.5mEq/L and ≥5.5mEq/L, respectively]. In-hospital and long-term mortality risks were also higher for patients with serum potassium levels of ≤3.5mEq/L. Conversely, ventricular arrhythmias were higher only for patients with serum potassium level of ≤3.5mEq/L. Furthermore, a significant relationship was found between the patient with serum potassium levels of ≤3.5mEq/L and ventricular arrhythmias.

The first six-month clinical outcomes and risk factors associated with high on-treatment platelet reactivity of clopidogrel in patients undergoing coronary interventions.

OBJECTIVE: This study attempted to fill the gaps in evidence related to response to clopidogrel treatment in the Turkish population. The study aimed to determine the prevalence, associated risk factors, and clinical outcomes of high on-treatment platelet reactivity (HTPR) of clopidogrel in patients undergoing percutaneous coronary intervention (PCI) in a tertiary cardiovascular hospital in Turkey. METHODS: In this prospective studied a total of 1.238 patients undergoing PCI were included in the present study. Blood samples were analyzed using a Multiplate analyzer. All patients were examined in the outpatient clinics at the end of the first and sixth months for recording drug therapy compliance and study endpoints. RESULTS: Among the study population, 324 (30.2%) patients were found to have HTPR (mean age 58.03±11.88 years, 71.7% men). The incidence of HTPR was higher amongst females than amongst males (38.3% vs. 27%, p=0.010). Hypertension and diabetes mellitus were more frequently observed in the HTPR group (57.7% vs. 48.7%, p=0.004; 35% vs. 29.1%, p=0.040, respectively). When the recorded data were analyzed using multinomial regression analysis, hypertension, hemoglobin level, platelet, lymphocyte, and eosinophil count were independently associated with HTPR. CONCLUSION: On the basis of the results obtained from our study, we conclude that 30.2% of the Turkish population has HTPR. Our results also led us to believe that hypertension is an associated risk factor and decreased hemoglobin level as well as increased platelet counts are laboratory parameters that are strongly associated with the presence of HTPR. However, no differences were observed with regard to cardiovascular mortality and stent thrombosis.

Risk factors and outcomes in patients with ectatic infarct-related artery who underwent primary percutaneous coronary intervention after ST elevated myocardial infarction.

OBJECTIVE: We aimed to assess the risk factors for coronary artery ectasia (CAE) as infarct-related artery (IRA) and short-term and 1 year outcomes. BACKGROUNDS: CAE in patients with ST elevated myocardial infarction (STEMI) is a rare condition with a limited knowledge about the risk factors associated with coronary artery ectasia in STEMI and prognosis after primary percutaneous coronary interventions. METHODS: Retrospectively, 1655 patients with STEMI who were undergone coronary angiography were included in this study. Patients were divided into two groups according to their coronary anatomy as ectasia and control groups. Demographic features, angiographic results, and clinical events were compared. Multivariate analysis was performed to assess the association of the features with CAE in STEMI. RESULTS: In total, 1655 patients (99 patients in CAE group vs 1556 patients in control group) were analyzed. Hypertension and smoking were significantly higher in CAE group. No-reflow rates were significantly higher (13.1% vs 5.4%, p = 0.004) in CAE group. In-hospital mortality rates were similar between the groups. Difference in revascularization rates (8.1% vs 9.6%, p = 0.39) and death in 1 year (6.1% vs 4.9%, p = 0.37) were also nonsignificant between the groups. According to results of the multivariate analysis, hypertension (Odds ratio (OR): 1.71 (1.14-2.58), p = 0.01) and smoking (OR: 1.98 (1.32-2.99), p = 0.001) remained significantly associated with coronary ectasia. CONCLUSION: In conclusion, despite being higher no-reflow rates, short-term and 1 year survival and revascularization rates were similar between the groups. Additionally, hypertension and smoking were associated with CAE as IRA. © 2016 Wiley Periodicals, Inc.
