Ongoing research on Coronavirus Disease 2019 (COVID-19) infection has revealed that it is associated with serious damage to many organs, not only the lungs. This infection can also affect the cardiovascular system and lead to serious cardiac pathologies. In this article, we present a case of transient bradyarrhythmia in a patient who was diagnosed with COVID-19 and recovered spontaneously with treatment. A 74-year-old male patient was hospitalized with symptomatic COVID-19 infection. At the time of hospitalization, the patient was asymptomatic from a cardiac standpoint, but was found to have sinoatrial exit block type 2-2, intermittent Mobitz type 2 atrioventricular block, and sinus bradycardia. The medical team decided to closely monitor the patient, who responded well to COVID-19 treatment and did not develop bradyarrhythmia as his symptoms improved. Patients with COVID-19 infection should be closely monitored for bradyarrhythmia. Permanent pacemaker should not be rushed in these patients.

Background and Objectives: Contemporary studies have shown that low ejection fraction (EF) is a significant predictor of sudden cardiac death in ischemic heart failure. However, relying solely on EF and waiting 90 days for ICD implantation is inadequate for preventing sudden death in STEMI patients. Materials and Methods: This study aims to explore if left ventricular global longitudinal strain (GLS) measured at discharge can predict EF < 35% at the third-month follow-up in STEMI patients with impaired systolic function (EF < 35%). The study involved 69 patients diagnosed with STEMI. The results from 29 patients with EF ≤ 35% and 40 patients with EF between 36 and 49% were compared. Echocardiographic images were recorded, and the LV GLS value was measured. Results: In both univariate and multivariate regression analyses, LV GLS at discharge was the only independent predictor of EF ≤ 35% after three months. An LV GLS value below 9.55% at discharge predicted an EF below 35% at 90 days, with 75% sensitivity and 76.5% specificity (AUC = 0.814, p = 0.005). Conclusions: Current guidelines recommend waiting three months before ICD implantation in STEMI patients with EF ≤ 35%, but this study suggests that low GLS can help identify high-risk patients earlier, potentially reducing the waiting period for ICD implantation.

Pentoz monofosfat yolu aracılığı ile glukoz-6-fosfat dehidrogenaz (G6PD) enzimi eritrositleri ve hemoglobin moleküllerini oksidatif strese karşı korur. Dünyadaki en sık enzim eksikliği olarak görülen G6PD enzim eksikliğinde; akut hemolitik anemi, yenidoğan sarılığı, favizm ve kalıtsal sferositik olmayan hemolitik anemi gibi klinik durumlar görülür. Akut koroner sendrom esnasında genel klinik duruma bağlı oluşan oksidatif ajanlar ve koroner anjiyografi öncesi ve sırasında uygulanan medikasyonlar hemolitik ve trombotik krize neden olabilirler. Bu yazıda G6PD eksikliği bulunan 64 yaşındaki kadın hastaya akut koroner sendrom tanısı ile perkütan koroner girişim (PKG) sırasında ve takibinde gelişen yaygın koroner tromboz vakasını sunduk.
