Prolonged corrected QT interval in hospitalized patients with coronavirus disease 2019 in Dubai, United Arab Emirates: a single-center, retrospective study.

Objective: To evaluate the association of a prolonged corrected QT (QTc) interval in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and its association with in-patient mortality.

Methods: A cohort of 745 patients were recruited from a single center between 1 March 2020 and 31 May 2020. We analyzed the factors associated with a prolonged QTc and mortality.

Anomalous left anterior descending artery: an uncommon cause of ST elevation myocardial infarction.

A healthy 32-year-old Asian man presented in emergency with a history of severe chest pain. ECG showed normal sinus rhythm with ST elevations in the anterior chest leads. He was diagnosed with anterior wall ST segment elevation myocardial infarction and was thrombolysed with tenecteplase.

Characteristics of Patients With Diabetes Having Normal Coronary Arteries.

We evaluated the association between risk variables in diabetic patients with normal and diseased coronary arteries in a retrospective cohort study conducted at Rashid Hospital, Dubai. A total of 4446 patients underwent coronary angiography due to various indications; 43% had type 2 diabetes mellitus (T2DM). Among the diabetic patients, 94% had diseased coronary arteries and the remaining 6% had absolutely normal arteries.

Mitral valve prolapse and electrolyte abnormality: a dangerous combination for ventricular arrhythmias.

A 27-year-old woman with a history of bileaflet mitral valve prolapse and moderate mitral regurgitation presented to our emergency with untractable polymorphic wide complex tachycardia and unstable haemodynamics. After cardiopulmonary resuscitation, return of spontaneous circulation was achieved 30 min later. Her post-resuscitation ECG showed a prolonged QT interval which progressively normalised over the same day.

Myocardial infarction in a young man due to coronary artery aneurysms after an undiagnosed Kawasaki disease.

Background: Kawasaki disease usually affects infants and young children. It often goes unrecognized in adults due to varying symptoms and lack of definite diagnostic criteria.

Objectives: To describe the potential for acute myocardial infarction as a complication of antecedent Kawasaki Disease (KD).

Intracranial haemorrhage 4 days after receiving thrombolytic therapy in a young woman with myocardial infarction.

Intracranial haemorrhage is a known complication after fibrinolytic therapy and occurs usually in the first 24 h. We report a 35-year-old woman who presented with severe central chest pain and she was diagnosed as anterior ST elevation myocardial infarction. She was given fibrinolytic therapy with Tenecteplase.

An unexpected diagnosis in a dyspnoeic patient with primary Sjogren syndrome.

We describe a case of a 50-year-old lady with newly diagnosed primary Sjogren syndrome who presented with severe pulmonary artery hypertension and pericardial effusion. She was managed by immunosuppressive agents and a combination of standard therapy for pulmonary hypertension. Our patient had a clinically significant involvement of cardio-pulmonary system that is atypical of this disease.

A unique presentation of four thrombotic events at a time.

A 72-year-old man was referred to our hospital as a case of postcardiac arrest following a long distance air flight. Work-up in the emergency department revealed the presence of deep vein thrombosis (DVT), bilateral pulmonary embolism, inferior STEMI (ST elevation myocardial infarction) and ischaemic stroke. He received thrombolysis by recombinant tissue plasminogen activator (tPA) following which his haemodynamic status improved, but he developed haemorrhagic transformation of the stroke as a complication.

Endomyocardial fibrosis causing stroke in a young man.

An Indian man in his late 30s presented with ischaemic stroke and eosinophilia of 711/mm(3). ECG showed first-degree heart block with ST depression and symmetrical T-wave inversions in the chest leads. Subsequently, the patient was further evaluated by echocardiography and cardiac MRI which identified the presence of endomyocardial fibrosis in the heart.
