    Abstract Background Recent studies have demonstrated that the frontal QRS-T angle, defined as the angle between the mean QRS and T vectors, is a strong independent predictor of mortality in patients with cardiovascular disease and in the normal population. In this study, we aimed to investigate the relationship between frontal QRS-T angle and in-hospital mortality in COVID-19 patients. Methods A total of consecutive 532 patients with positive polymerase chain reaction (PCR) tests were enrolled. The patients were divided into two groups as in-hospital mortality and survival groups. Frontal QRS-T angle was automatically calculated from the admission electrocardiography (ECG). Results The median age in the study population was 62 (49-72) years and 273 (51.4%) of the patients were male. The median frontal QRS-T angle was 40 degrees (20-67 IQR) in the in-hospital mortality group, while it was 27 (11-48 IQR) in the survival group (p=0.001). In multivariable logistic regression analysis, frontal QRS-T angle was found to be an independent predictor of mortality (Odds ratio (OR):1.01, 95% Confidence interval (CI):1.00-1.02, p=0.036). Conclusion Frontal QRS-T angle, which was observed wider in the in-hospital mortality group, was found to be associated with in-hospital mortality in patients hospitalized for COVID-19.

    Abstract Purpose: Cardiac involvement in limb-girdle muscular dystrophy (LGMD)2A and LGMD2B, the most common subgroups of LGMD, is controversial. Our study aims to determine whether myocardial dysfunction develops in LGMD2A and LGMD2B patients.
    Methods: The study included 16 LGMD2A, 12 LGMD2B patients, and 48 healthy individuals. Comparisons included demographic, clinical, and laboratory parameters of LGMD2A and LGMD2B subgroups and traditional echocardiography and two-dimensional speckle tracking echocardiography (2D-STE) parameters with the normal population.
    Results: The median age was 33 (22-39 interquartile range [IQR]) in the LGMD2A group, 33 (27-38 IQR) in the LGMD2B group, and 28 (25-35 IQR) in the control group. The left ventricular (LV) ejection fraction of both LGMD2A and LGMD2B groups was similar to the control group (p = 0.296 and p = 0.918). Apical 4-chamber longitudinal strain (LS), Apical 2-chamber LS, Apical 3-chamber LS, left ventricular global longitudinal strain (LVGLS)-mid-myocardial, LVGLS-endocardium, and LVGLS-epicardium were lower (less negative) in the LGMD2B group compared to the control group (p = 0.006, p = 0.001, p < 0.001, p < 0.001, p < 0.001, and p < 0.001, respectively).
    Conclusion: LV 2D-STE parameters of LGMD2A patients were similar to the control group, while they decreased significantly (less negative) in LGMD2B patients, indicating that LV subclinical myocardial dysfunction may develop in LGMD2B patients.

    Abstract Background: Myotonic dystrophy type 1(MD1), which is characterized by decreased muscle tone, progressive muscle weakness, and cardiac involvement, is an autosomal dominant and progressive congenital muscle disease. Cardiac involvement more often manifests as conduction abnormalities and arrhythmias (such as supraventricular or ventricular). Approximately one-third of MD1-related deaths occur due to cardiac causes. The index of cardiac-electrophysiological balance (ICEB) is a current parameter calculated as QT interval/QRS duration. The increase in this parameter has been associated with malignant ventricular arrhythmias. In this study, our aim was to compare the ICEB values ​​of MD1 patients and the normal population.
    Material and method: A total of 62 patients were included in our study. They were divided into two groups - 32 MD patients and 30 controls. The demographic, clinical, laboratory, and electrocardiographic parameters of the two groups were compared.
    Results: The median age of the study population was 24 (20-36 IQR), and 36 (58%) of these patients were female. Body mass index was higher in the control group (p = 0.037). While in the MD1 group creatinine kinase was significantly higher (p <0.001), In the control group creatinine, aspartate aminotransferase, alanine aminotransferase, calcium, and lymphocyte levels were significantly higher (p=0.031, p= 0.003, p=0.001, p=0.002, p=0.031, respectively). ICEB [3.96 (3.65-4.46) vs 3.74 (3.49-3.85) p=0.015] and corrected ICEB (ICEBc) [4.48 (4.08-4.92) vs 4.20 (4.03-4.51) p = 0.048] were significantly higher in the MD1 group.
    Conclusion: In our study, ICEB was found to be higher in MD1 patients than in the control group. Increased ICEB and ICEBc values ​​in MD1 patients may precipitate ventricular arrhythmias in the future. Close monitoring of these parameters can be helpful in predicting possible ventricular arrhythmias and in risk stratification.

    Abstract Objective: We aimed to examine the effects of COVID-19 pneumonia on cardiac ischemia detected by myocardial perfusion imaging with single-photon emission computed tomography myocardial perfusion imaging (SPECT-MPI) in patients presenting with chest pain and shortness of breath after recovery from COVID-19.
    Materials and method: Patients with a history of COVID-19 confirmed by reverse transcriptase-PCR test who underwent SPECT-MPI for the evaluation of ischemia with the complaints of chest pain and shortness of breath were screened for this study. Patients who underwent thorax CT during the acute period of the COVID-19 were included. Patients with and without pneumonia were determined based on computed tomographic criteria. The patients with a summed stress score of at least 4 on SPECT-MPI were considered to have abnormal MPI in terms of ischemia.
    Results: A total of 266 patients were included in the study. Sixty-five (24%) patients had ischemia findings on SPECT-MPI. Thorax CT showed pneumonia in 152 (57%) patients, and the patients were divided into two groups as pneumonia and nonpneumonia. Abnormal SPECT-MPI scores, which represented myocardial ischemia, were higher in the pneumonia group. Multivariate logistic regression analyses showed that the presence of hyperlipidemia and pneumonia on CT increased the risk of ischemia on SPECT-MPI (OR, 2.08; 95% CI, 1.08-3.99; P-value = 0.029; and OR, 2.90; 95% Cl, 1.52-5.54; P-value = 0.001, respectively).
    Conclusion: COVID-19 pneumonia was identified as an independent predictor of ischemia on SPECT-MPI. Symptoms including chest pain and shortness of breath in patients who have had COVID-19 pneumonia may be attributed to coronary ischemia.

    Abstract Background: Thrombolysis in Myocardial Infarction Frame Count (TFC) is an index that provides a quantitative evaluation of coronary microvascular dysfunction. In this study, we aimed to examine the effect of COVID-19 infection on TFC in patients admitted with chest pain and dyspnoea after COVID-19 disease and had abnormal findings in myocardial perfusion scintigraphy.
    Methods: For this single-center retrospective study, patients with and without a history of COVID-19 who were underwent coronary angiography for abnormal findings in myocardial perfusion scintigraphy between January 1, 2021 and June 30, 2021 were analysed. Patients were divided into two groups as patients with COVİD-19 history and those without. After exclusion criteria, patients with adequate angiographic monitoring and data were included in the study.
    Results: A total of 210 patients, 48 with a history of COVID-19, were included in the study. The mean age was ±55 10 years, and 122 (58%) patients were women. In patients with a history of COVID-19, TFC was significantly higher in the LAD (
    Conclusion: TFC may be elevated due to coronary microvascular dysfunction in patients with a history of COVID-19.

    Abstract Hypertension is a major concomitant disease in hospitalized patients with COVID-19 (Coronavirus disease 2019) infection. The adverse effect of hypertension on prognosis in COVID-19 is known. Nevertheless, it is not known how COVID-19 progresses in resistant hypertensive patients. In this study, we aimed to examine the effect of resistant hypertension (ResHT) on in-hospital mortality in patients hospitalized with COVID-19. In our single-center retrospective study, included 1897 COVID-19 patients. The patients were divided into three groups according to the non-hypertensive (n = 1211), regulated HT (RegHT) (n = 574), and ResHT (n = 112). These three groups were compared according to demographic features, clinical signs, laboratory findings, and follow-up times. The median age of the study population was 62 (50-72 IQR) and 1000 (52.7%) of patients were male. The total mortality of the study population was 18.7% (n = 356). Mortality rates were similar in the hypertensive patient group (27.5% for the RegHT and 32.1% for ResHT, p = 0.321). In a multivariable analysis, ResHT was independently associated with a significantly increased risk of in-hospital mortality of COVID-19, while no significant increased risk was observed with RegHT [respectively, Odds Ratio (OR) = 2.013, Confidence Interval (CI) 1.085-3.734, p = 0.026 and OR = 1.194, CI 0.795-1.794, p = 0.394]. Also, age, male gender, chronic renal failure, lymphocyte, procalcitonin, creatinine, and admission SpO2 levels were determined as independent predictors of in-hospital mortality. In our study, it was found that ResHT was an independent predictor of mortality in patients hospitalized with COVID-19; however, this situation was not found in RegHT.

    Abstract Introduction: We have aimed to investigate the relationship between use of angiotensin-converting-enzyme inhibitor (ACEI) or angiotensin-receptor-blocker (ARB) drugs and acute hypoxemic respiratory failure (AHRF) and in-hospital mortality in hypertensive Covid-19 patients.
    Material and method: Consecutive 1345 patients diagnosed with Covid-19 between April and October 2020 who met inclusion criteria were divided into two groups based on presence and absence of AHRF and mortality. The groups were compared regarding epidemiological, clinical, radiological, laboratory findings and treatments methods. The patient groups ACEI, ARB and other antihypertensive drugs (non-ACEI/ARB) were compared regarding same parameters.
    Results: Median age was 68 (60-76) years in the patient group including 805 (59.9.1%) females. Of the patients, 475 (35.3%), 644 (47.9%) and 226 (16.8%) were using ACEIs, ARBs and non-ACEI/ARB, respectively. AHRF and in-hospital mortality developed in 1053 (78.3%) and 290 (21.6%) patients, respectively. Age, gender, coronary artery disease, diabetes mellitus (DM), neutrophil, lymphocyte, creatinine, D-dimer, C-reactive protein (CRP), ACEI, beta blocker and aspartate transaminase (AST) found statistically significant in the univariable logistic regression performed to identify independent predictors of mortality were included multivariable logistic regression model. Age (OR: 1.066, 95%CI: 1.049-1.083;
    Conclusion: In our study, it was not detected clinically significant difference between three groups with regard to their relation with in-hospital mortality.

    Abstract We aimed to examine the effect of a history of COVID-19 on myocardial ischemia in single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) in patients who presented with shortness of breath and/or chest pain after recovery. For this single-center retrospective study, patients who presented at cardiology outpatient clinics and had SPECT-MPI were screened. A total of 1888 patients were included in the study, 340 of whom had a history of COVID-19. 64 patients with > 50% stenosis on coronary angiography were excluded from the study. The primary outcome of the study was abnormal MPI. In the study population, the median age was 56 (49-64 IQR) years, and 1127 (65%) of the patients were female. Abnormal MPI was detected in 77 patients (23%) in the COVID-19 group and in 244 patients (16%) in the non-COVID-19 group. After adjustment was performed for clinical predictors using Bayesian logistic regression, an important association was found between the presence of a confirmed prior COVID-19 infection and abnormal MPI (posterior median odds ratio, 1.70 [95% CrI, 1.20-2.40], risk difference, 9.6% [95% CrI, 1.8%, 19.7%]). In SPECT-MPI, ischemia rates were observed to be higher in COVID-19 group and it was found that a confirmed prior COVID-19 might predict of abnormal MPI.
