Takotsubo Syndrome (TTS) is characterized by transient left ventricular dysfunction, often triggered by emotional or physical stress. While negative emotional events are common triggers, positive emotional events can also induce a rare variant known as Happy Heart Syndrome (HHS). This case report describes a 53-year-old male who presented with acute chest pain following a positive emotional stimulus: a birthday call offering him an opportunity to play with his favorite music group. Initial workup suggested an acute myocardial infarction, but coronary angiography revealed no obstruction. Left ventriculography showed the classic apical ballooning pattern of TTS. The patient was diagnosed with HHS. This case underscores the importance of considering positive emotional triggers in the diagnosis of TTS and highlights the need for further research into its diverse presentations and management ...

Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease with an important course due to systemic compromise. SLE is frequently associated with antiphospholipid syndrome, and pulmonary thromboembolism (PE) is particularly common. It is extremely rare for PE to be the initial clinical presentation and even more uncommon for it to coincide with cardiac tamponade, representing a challenge in diagnosis and management. We present a case of a 42-year-old woman with recurrent PE with severe pleural and pericardial effusion, hemodynamic instability, and cardiac tamponade. Laboratory workup revealed hypocomplementemia, leukopenia, negative SLE antibodies, and a positive lupus anticoagulant. This case emphasizes the importance of determining the etiology of PE, assessing risk classification, and implementing proper management, which are crucial for the patient's survival an...

Objective. Acute myocardial infarction-related cardiogenic shock (AMI-CS) is often accompanied by tachycardia, which, in turn, increases myocardial oxygen consumption and hinders the use of ventricular assist devices, such as intra-aortic balloon pump. Evidence suggests that ivabradine may reduce heart rate (HR) without affecting other hemodynamic parameters. The aim of the present study was to determine the effect of ivabradine on reducing HR and changes in other hemodynamic parameters such as cardiac index (CI), in patients with AMI-CS and tachycardia. Materials and methods. A single-center, open label, randomized clinical trial included patients diagnosed with AMI-CS and tachycardia with >100 beats per minute (BPM). Heart rate, cardiac index, and other hemodynamic parameters measured by pulmonary flotation catheter were compared at 0, 6, 12, 24, and 48 hours after randomization. Re...
