Background: Takotsubo syndrome (TTS), a stress-induced transient left ventricular dysfunction, remains poorly understood, with an estimated incidence of 1-2 % among acute coronary syndrome cases. This study investigates racial and ethnic disparities in hospital outcomes and clinical characteristics of TTS., Methods: We conducted a retrospective cohort study using the National Inpatient Sample data from 2016 to 2020, identifying TTS cases through validated ICD-10 codes. Statistical analysis was performed using Stata 18, with logistic regression models adjusting for confounders to identify disparities in outcomes., Results: The study included 32,785 TTS hospitalizations; the majority were White (80.5 %), followed by Black (6.7 %) and Hispanic (5.8 %) patients. Minority groups, mainly Black and Hispanic patients, were younger (average age 63) and predominantly from lower-income brackets, while Asians had the highest income bracket. Length of stay (5.1 days) and Total cost ($22,707.60) were highest among Native Americans. Notable findings include Black patients showing the highest rate of stroke (4.8 %, OR 2.1, 95 % CI 1.2 to 3.4, p = 0.003). The rate of cardiogenic shock was highest among Asians (11 %, OR 2, 95 % CI 1.5 to 2.5, p < 0.001). Mortality rates were elevated in Black (2 %, OR 1.5, 95 % CI 1.3 to 1.7 p < 0.001) and Asian populations (1.8 %, OR 1.97, 95 % CI 1.5 to 2.5, p < 0.001)., Conclusion: Significant racial and ethnic disparities exist in TTS outcomes, with minority groups having more in-hospital outcomes. These findings highlight the urgent need for targeted interventions and further research to reduce healthcare inequities in TTS management., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Pericardial effusion, commonly associated with malignancies such as lung, breast, and esophageal cancers through local extension, or leukemia, lymphoma, and melanoma via metastatic dissemination, is rarely observed in renal cell carcinoma (RCC). This report presents a rare case of a large loculated pericardial effusion in a 68-year-old male, potentially linked to RCC, who concurrently presented with an inferior wall ST-elevation myocardial infarction (STEMI). The patient, with a history of hypertension, hyperlipidemia, end-stage renal disease, coronary artery disease, and former smoking, exhibited symptoms including chest pain, diaphoresis, and shortness of breath, but no fever, chills, or night sweats. Diagnostic imaging revealed a significant pericardial effusion and a renal mass consistent with RCC, along with potential pulmonary metastases. Despite the complexity and high-risk nature of his condition, exacerbated by recent STEMI and dual antiplatelet therapy, a multidisciplinary approach was employed. This case emphasizes the need for careful management and tailored treatment strategies in patients with multiple coexisting conditions, highlighting the critical role of comprehensive diagnostic evaluation and collaborative care in improving patient outcomes., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Aim: To investigate the relationship between coronary artery lesion severity determined using the baseline SYNTAX score and sleep problems that might occur after discharge determined using the Pittsburgh Sleep Quality Index (PSQI)., Methods: This prospective study included patients with first acute coronary syndrome (ACS) who underwent percutaneous coronary angiography between February 2019 and August 2019. The severity of coronary artery stenosis was classified according to coronary angiography and SYNTAX scores. Patients were grouped as those with a SYNTAX score of ≤22 and >22. Sleep quality after discharge was classified according to the PSQI. PSQI ≤5 represented good sleep quality, and PSQI >5 represented poor sleep quality. Univariate and multivariate logistic regression was used to investigate the relationship between sleep quality and coronary artery stenosis severity., Results: A total of 424 patients were included in the study. Of these, 294 (69.34%) had a SYNTAX score of ≤22 and 130 (30.66%) had a SYNTAX score of >22. The mean age of all patients was 60.37 ± 12.23 years, 59.69 ± 11.85 years in the SYNTAX ≤22 groups and 61.90 ± 12.98 years in the SYNTAX >22 group (P = 0.086). The majority (78.54%) of the patients were male and there was no significant difference between the SYNTAX ≤22 group and the SYNTAX >22 group in terms of sex distribution (P = 0.383). According to the univariate logistic regression analysis, age (P = 0.014), diabetes (P = 0.027), left ventricular ejection fraction (P = 0.001), estimated glomerular filtration rate (P = 0.039), creatine kinase MB (P = 0.040) and SYNTAX scores (P < 0.001) were significantly associated with high PSQI global scores (>5). However, according to the multivariate logistic regression analysis results, high (>22) SYNTAX scores were the only factor independently associated with the high (>5) PSQI global scores [odds ratio, 3.477; 95% confidence interval (CI), (2.190-5.522); P < 0.001]. Complete revascularization group had significantly higher sleep latency and sleep duration time, sleep efficiency and the percentage of patients with PSQI global score of ≤5 than the incomplete revascularization group (P < 0.001 for all)., Conclusion: Among patients with ACS, those with high SYNTAX scores should be monitored more carefully for sleep disorders that may occur later., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objective: COVID-19 infection is known to injure myocardial tissue and increase arrhythmic events. However, data on the subject is limited in the literature. In our study, our aim was to investigate possible arrhythmic damages in COVID-19 survivors using the frontal plane QRS-T [f(QRS)-T] angle and a few other ECG parameters., Patients and Methods: 269 patients who recovered from COVID-19 between April 2020 and January 2021 were included into the study. Pre-admission electrocardiograms and first-month outpatient clinic control ECGs of the patients were compared., Results: After COVID-19, left bundle branch block (p<0.001), right bundle branch block (p<0.001), right bundle branch block (p<0.001), and atrial fibrillation (p<0.001) rates had increased. Prolongation was detected in QRS duration (p<0.001), QT interval (p=0.014), adjusted QT interval (p=0.007) and Tpe interval (p=0.012). F(QRS)-T angle (p<0.001) and fragmented QRS rate (p<0.001) were increased., Conclusions: It was observed in our study that even if patients survived COVID-19, permanent deterioration in ECG parameters may occur.

BACKGROUND Myocarditis is cardiac muscle inflammation caused by infectious or noninfectious agents. Rarely, clozapine, an atypical antipsychotic drug used to treat resistant schizophrenia, has been reported to cause myocarditis, as we report in this case. CASE REPORT A 29-year-old man, who was known to have schizophrenia and was on olanzapine therapy, presented in our Emergency Department with active psychosis, and was subsequently admitted to the psychiatric ward for refractory schizophrenia. He was started on clozapine, which was cross-titrated with olanzapine. On day 20 of being treated with clozapine, he developed a high-grade fever and chest pain. EKG demonstrated new-onset prolonged QT corrected for heart rate (QTc), premature ventricular contractions, ST-T wave changes with an increased ventricular rate, and ventricular bigeminy with elevated troponin and inflammatory markers. Echocardiography showed a reduced left ventricular ejection fraction. Coronary angiography showed normal coronary arteries, low cardiac output, and cardiac index consistent with cardiogenic shock was also observed. Other pertinent laboratory results included negative respiratory viral panel, including COVID-19 PCR, negative blood cultures, and negative stool screen for ova and parasite. Clozapine was discontinued and the patient received management for heart failure with reduced ejection fraction. He improved clinically with return of EKG to normal sinus rhythm and improved left ventricular ejection fraction on repeat echocardiogram. CONCLUSIONS Acute myocarditis can occur due to a myriad of causes, both infectious and noninfectious; thus, determining the lesser-known causes, such as drug-related etiology, is essential to provide appropriate treatment for patients.

Background: Coronavirus 2019 (COVID-19) causes morbidity and mortality in an increasing number of people worldwide. Although it mainly affects the respiratory system, it influences all organs, including the heart. It is associated with a broad spectrum of widespread cardiovascular problems ranging from mild myocardial injury to fulminant myocarditis. We aimed to evaluate the presence and prevalence of cardiac involvement in asymptomatic or symptomatic patients after they recovered from COVID 19 infection., Methods: A total of 100 consecutive patients with COVID-19 proven by reverse transcription polymerase chain reaction (RT-PCR), under 40 years of age and without any known additional chronic diseases were analyzed retrospectively for cardiac magnetic resonance (CMR) results and symptoms., Results: Cardiac involvement was detected in 49 out of 100 patients on CMR imaging. In the cardiac involvement group, the number of patients with chest pain and/or dyspnea was 41 (84%), which was statistically significant (p = 0.001). Twenty-four patients (47%) in the without cardiac involvement group were asymptomatic and this was also statistically significant (p = 0.001). LV ejection fraction was statistically significantly lower in the group with cardiac involvement (61% vs 66%, p = 0.001). LV stroke volume and tricuspid annular plane systolic excursion (TAPSE) were statistically significantly lower in patients with cardiac involvement (p = 0.028 and p = 0.019, respectively)., Conclusion: Based on single center experience, myocardial involvement is common in symptomatic patients after COVID-19. More studies are needed for long-term side effects and clinical results in these patients., (© 2021 Wiley Periodicals LLC.)

Background: The importance of monocyte count-to-HDL-cholesterol ratio (MHR) in cardio- vascular diseases has been shown in various studies. Ascending aortic dilatation (AAD) is a common complication in the patients with bicuspid aortic valve. In this study, we aimed to investigate the relationship between MHR and the presence of aortic dilatation in the patients with bicuspid aortic valve., Methods: The study population included totally 347 patients with bicuspid aortic valve.169 patients with aortic dilatation (ascending aorta diameter ≥ 4.0 cm) and 178 patients with no aortic dilatation. Echocardiographic and laboratory measurement was done and compared between groups., Results: The mean age of the participants was 44.7 ± 15.4 years and average ascending aorta diameter was 3.2 ± 0.3 cm in dilatation negative group and 4.4 ± 0.4 cm in positive group. MHR was significantly increased in in patients with aortic dilatation. MHR and uric acid level was independently associated with the presence of aortic dilatation in the patients with bicuspid aortic valve., Conclusion: We found a significant relationship between MHR and aortic dilatation in the patients with bicuspid aortic valve., (© 2021 Acar B et al.)

Background: The evaluation of thromboembolic risk is the cornerstone of atrial fibrillation (AF) management. Thromboembolic risk is associated with the presence of left atrial (LA) thrombus and spontaneous echo contrast (SEC), namely the thromboembolic milieu., Aims: We aimed to assess the predictors of the thromboembolic milieu in terms of LA thrombus and/ or SEC in patients with paroxysmal AF undergoing electrical cardioversion or catheter ablation, and to develop an effective risk model for detecting the thromboembolic milieu., Methods: We included a total of 434 patients with nonvalvular paroxysmal AF who underwent transesophageal echocardiography prior to cardioversion or catheter ablation., Results: In patients with the thromboembolic milieu, total protein and C‑reactive protein levels, LA diameter, and systolic pulmonary artery pressure (SPAP) were higher, while left ventricular ejection fraction (LVEF) was lower than in patients without the thromboembolic milieu. In a multivariate logistic regression analysis, age, total protein levels, LVEF, LA diameter, and SPAP were independent predictors of LA thrombus and/or SEC. In a receiver operating characteristic curve analysis, the optimal cutoff values for the discrimination of patients with the thromboembolic milieu were as follows: 60 years for age; 7.3 mg/dl for total protein; 40% for LVEF; 40 mm for LA diameter; and 35 mm Hg for SPAP. Based on these cutoff values, we developed a novel risk model, namely, the PALSE score. The area under the curve for the PALSE score was 0.833. Patients with a PALSE score lower than 1 did not show thrombus or spontaneous echo contrast., Conclusions: The PALSE score, which includes total protein levels, age, LA diameter, SPAP, and LVEF, seemed to accurately predict the presence of the thromboembolic milieu in patients with paroxysmal AF.

We evaluated the relationship between nesfatin-1 and acute myocardial infarction (AMI) and Mediterranean diet scores. 67 patients with AMI and 33 patients with normal coronary arteries (control group) were included in the study. The patients with AMI were divided into 2 groups based on low (<32) (n = 33) and high values of the synergy between percutaneous coronary intervention with Taxus and cardiac surgery (SYNTAX) scores (≥34) (n = 35). Mediterranean diet score, serum nesfatin-1 concentrations and all other data were compared between the groups. Serum nesfatin-1 concentrations were significantly lower in 67 AMI patients (both the high and low SYNTAX groups) than in the control group (p < 0.001). Moreover, serum nesfatin-1 concentrations were lower in the high SYNTAX group than those in the low SYNTAX group (p < 0.001). There were positive correlations between the serum nesfatin-1 concentrations and Mediterranean diet scores in both the AMI patients and the control subjects, and there was a negative correlation between the serum nesfatin-1 concentrations and SYNTAX scores in the AMI patients. This study has shown that serum nesfatin-1 concentrations are closely related to the severity of AMI and Mediterranean diet scores., (Copyright © 2019 Elsevier Inc. All rights reserved.)
