Evaluation of Index of Cardiac Electrophysiological Balance in Patients With Myotonic Dystrophy Type 1.

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 effect of coronavirus disease 2019 pneumonia on myocardial ischemia detected by single-photon emission computed tomography myocardial perfusion imaging.

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.

The effect of prior COVID-19 infection on coronary microvascular dysfunction.

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.

The relationship of frontal QRS-T angle between patients with newly diagnosed true and white coat hypertension.

Objectives: The frontal QRS-T (f-QRST) angle is a measure of depolarization and repolarization heterogeneity and may be a predictor of poor ventricular health. We aimed to investigate whether the f-QRST angle indicates myocardial damage and predicts newly diagnosed true hypertension (HT) in patients with white coat hypertension.

Methods: We measured the f-QRST angle of 63 subjects with WHC and 105 patients with newly diagnosed HT.

The relationship between mean platelet volume and resistant hypertension.

Objective: Resistant hypertension (RH) is associated with an increased risk of cardiovascular events.Mean platelet volume (MPV) has been shown to indicate platelet activation and is associated with increased cardiovascular disease risk. In our study, we aimed to evaluate the relationship between mean platelet volume and resistant hypertension.

SPECT myocardial perfusion imaging identifies myocardial ischemia in patients with a history of COVID-19 without coronary artery disease.

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.

Relationship between frontal QRS-T duration and the severity of coronary artery disease in who were non-diabetic and had stable angina pectoris.

Objective: There is a known relationship between frontal-QRS-T (F-QRS-T) angle and coronary artery disease (CAD). This study examined the relationship between F-QRS-T angle changes and CAD severity in patients with stable CAD.

Methods: A total of 202 patients were included in the study after the implementation of exclusion criteria among 894 patients, who were admitted to the outpatient clinic with stable angina pectoris between September 2018 and September 2019.

The effect of resistant hypertension on in-hospital mortality in patients hospitalized with COVID-19.

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.

The effect of chronic DOAC treatment on clinical outcomes of hospitalized patients with COVID-19.

Background: Recent findings indicate that thrombosis is one of the underlying pathophysiology and complication of COVID-19 infection. Therefore, the prognosis of the disease may be more favourable in people who were under oral anticoagulant treatment before the COVID-19 diagnosis. This study aims to evaluate the effects of chronic DOAC use on ICU admission and mortality in hospitalized patients due to COVID-19 infection.

The effect of RAAS inhibitors on acute hypoxemic respiratory failure and in-hospital mortality in the hypertensive Covid-19 patients.

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 effect of favipiravir on QTc interval in patients hospitalized with coronavirus disease 2019.

Background: The effect of favipiravir on the QTc interval during the treatment of Coronavirus Disease 2019 (COVID-19) patients is unclear. Thus, the current study objective was to evaluate any change in the QTc interval in patients who were hospitalized due to COVID-19 receiving favipiravir treatment.

Method: Patients hospitalized with COVID-19 were assessed in this single-center retrospective study.

The effect of ticagrelor based dual antiplatelet therapy on development of late left ventricular thrombus after acute anterior ST elevation myocardial infarction.

Aim: The aim of this study is to investigate the impact of ticagrelor as compared to clopidogrel based dual antiplatelet therapy (DAPT) during post-discharge management on the incidence of left ventricular (LV) thrombus in patients with first acute anterior ST elevation myocardial infarction (STEMI).

Method: 641 patients who met the inclusion criteria were divided into two groups based on the receipt of either ticagrelor or clopidogrel based DAPT.

Result: Left ventricular thrombus was detected in 73 (11.

Impact of Coronary Collateral Circulation on In-Hospital Death in Patients with Inferior ST Elevation Myocardial Infarction.

Objectives. Coronary collateral circulation (CCC) may limit the size of right ventricular (RV) infarcts but does not fully explain the relationship between CCC and clinical adverse events in patients with inferior STEMI. In this study, it was aimed to assess the relationship between preintervention angiographic evidence of CCC and clinical outcomes in patients with inferior STEMI who have undergone percutaneous coronary intervention.

Neutrophil/lymphocyte ratio is associated with right ventricular dysfunction in patients with acute inferior ST-segment elevation myocardial infarction.

Background: Acute inferior ST-segment elevation myocardial infarction (STEMI) is associated with increased in-hospital morbidity and mortality particularly among patients with coexisting right ventricular (RV) involvement. High neutrophil to lymphocyte ratio (NLR) is an independent predictor of major adverse cardiac events and mortality in patients with myocardial infarction. This study evaluated the relationship between the NLR and RV dysfunction (RVD) in patients with inferior STEMI who underwent primary percutaneous coronary intervention (PCI).

The neutrophil to lymphocyte ratio is associated with severity of rheumatic mitral valve stenosis.

Background: Rheumatic heart disease (RHD) is a serious health concern in developing countries. Rheumatic mitral stenosis (RMS) is the most long-term sequel in RHD. The neutrophil to lymphocyte ratio (NLR) is a novel marker, and a higher NLR has been associated with poor clinical outcomes in various cardiovascular disorders.
