Objective: Electrocardiographic alterations were investigated following the second dosage of COVID-19 mRNA vaccination. Methods: A total of 260 individuals after two doses of COVID-19 vaccine with Pfizer-BioNTech were included in the study. The electrocardiographic parameters recorded at baseline and approximately one week later after two doses of Pfizer-BioNTech vaccine were compared for all patients. Results: PR interval was increased and QTc maximum interval was decreased significantly after second dose COVID-19 mRNA vaccination. Baseline and post-second dose vaccination states regarding P wave dispersion and QT dispersion/Tp-e interval which have been recognized to imply inhomogeneous atrial conduction and heterogeneity in ventricular repolarization were similar between groups. Conclusion: Our findings suggest that there should be no concern related to asymptomatic involvement of the myocardium subsequent the second dose of COVID-19 mRNA vaccination., Amaç: Bu çalışmanın amacı, ikinci doz COVID-19 mRNA aşılamasından sonra elektrokardiyografik değişi-klikleri değerlendirmektir. Yöntem: Çalışmaya Pfizer-BioNTech ile iki doz COVID-19 aşısı yapılan toplam 260 hasta dahil edildi. Başlangıçta ve iki doz Pfizer-BioNTech aşısından yaklaşık 1 hafta sonra kaydedilen elektrokardiyo-grafik parametreler tüm hastalar için karşılaştırıldı. Bulgular: İkinci doz COVID-19 mRNA aşılamasından sonra PR aralığı arttı ve QTc maksimum aralığı önemli ölçüde azaldı. Sırasıyla ventriküler repolarizasyonda homojen olmayan atriyal iletimi ve heterojenliği yansıttığı varsayılan P dalgası dispersiyonu ve QT dispersiyonu/Tp-e aralığı ile ilgili olarak başlangıç ve ikinci doz aşılama durumları arasında anlamlı bir fark yoktu. Sonuç: Bulgularımız, ikinci doz COVID-19 mRNA aşılamasından sonra miyokardın asemptomatik tutulumu ile ilgili herhangi bir endişe olmaması gerektiğini düşündürmektedir.

Aim: Statins are one of the most important agents in the treatment of atherosclerotic peripheral arterial disease. We aim to compare high- and moderate-dose statin therapy in patients with lower extremity artery disease (LEAD) who have undergone percutaneous transluminal angioplasty (PTA). Patients and Methods: Ninety-four patients treated with PTA were selected consecutively and retrospectively and were divided into two groups according to the high- or moderate-dose statin treatments they were given. Groups were compared for the absence of restenosis and occlusion as primary patency and the need for reintervention in the treated arterial segment as secondary patency. All patients underwent computed tomography (CT) angiography or duplex scan one year after receiving PTA. Results: Coronary revascularization (p
