Introduction: Multiple abnormal electrocardiographic findings have been documented in patients experiencing acute pulmonary embolism. Although sinus tachycardia is the most commonly encountered rhythmic disturbance, subsequent reports have highlighted other findings. These include right bundle branch block, right axis deviation, nonspecific ST segment/T wave changes, and T wave inversion in the right precordial leads. To date, only a limited number of cases involving a complete atrioventricular block have been reported in acute pulmonary embolism.
Case Presentation: Here, we present the case of a 91-year-old woman with acute pulmonary embolism, whose initial electrocardiogram showed a complete atrioventricular block. She presented with presyncope and an initial blood pressure of 77/63 mmHg. Echocardiography confirmed signs of right ventricular dysfunction. Catheter-directed thrombolysis and a temporary pacemaker insertion were carried out sequentially. The following day, electrocardiography showed sinus rhythm with a left bundle branch block.
Discussion: The presence of a complete atrioventricular block in patients with acute pulmonary embolism serves as a clinical marker of high-risk status.

Preventive Lipid-Lowering Therapy and Interactions With Health Care in Patients Who Develop Premature Coronary Artery Disease.

Centre for Heart Lung Innovation, University of British Columbia, Vancouver, Canada.
Background: Rates of premature coronary artery disease (CAD) are stagnant, and the prevalence of cardiovascular risk factors in young and middle-aged adults is increasing. Lipid-lowering therapy (LLT) is effective in preventing CAD but is underutilized in younger patients. The reasons for and consequences of this underutilization are not fully understood.

We report the case of a previously independent 82-year-old female who experienced acute hemodynamic and respiratory deterioration requiring inotropic support due to a fat embolism during revision hip arthroplasty. Computed tomography pulmonary angiography demonstrated fat embolism, and transesophageal echocardiogram showed evidence of right ventricle strain and fat embolism in-transit in the right heart, as well as a moderate patent foramen ovale. Under transesophageal echocardiogram and intravascular ultrasound guidance, the Inari FlowTriever thrombectomy device was used successfully to retrieve the fat embolism with immediate hemodynamic improvement, no complications, and uneventful recovery.

Background: South Asians may be particularly susceptible to premature myocardial infarction (MI) owing both to conventional cardiovascular risk factors and practices distinctive to South Asia. Identifying modifiable risk factors for MI in these populations could inform prevention strategies. We have, therefore, studied conventional risk factors and other characteristics in relation to occurrence of first MI in Bangladesh.

Background: Lipopolysaccharide (LPS)-induced apoptosis of lung microvascular endothelial cells (ECs) is the main reason of lung edema and acute lung injury (ALI) in septic conditions. Telocytes (TCs) are a distinct type of interstitial cells found around the lung microvasculature, which may protect ECs through the release of shed vesicles. However, whether TCs protect against LPS-induced EC apoptosis and ALI has not been determined.

Anterior cord syndrome is a rare yet critical neurological condition that poses significant challenges in clinical management. We present the case of a 71-year-old male with a medical history of hypertension, uncontrolled type II diabetes mellitus, hypothyroidism, and end-stage renal disease requiring dialysis who presented to the emergency department with complaints of chills, back pain, abdominal pain, and vomiting episodes. Based on the severity of the patient's illness, it was decided that inpatient admission would be best.
