Cardiac tamponade in people living with HIV: a systematic review of case reports and case series.

BACKGROUND

Cardiac tamponade is a life-threatening condition requiring prompt diagnosis and therapeutic intervention. Diagnosis and management of cardiac tamponade in patients with human immunodeficiency virus (HIV) infection pose a major challenge for clinicians. This study aimed to investigate clinical characteristics, paraclinical findings, therapeutic options, patient outcomes, and etiologies of cardiac tamponade in people living with HIV.

METHODS

Pubmed, Embase, Scopus, and Web of Science databases were systematically searched for case reports or case series reporting HIV-infected patients with cardiac tamponade up to February 29, 2024. Baseline characteristics, clinical manifestations, paraclinical findings, therapeutic options, patient outcomes, and etiologies of cardiac tamponade were independently extracted by two reviewers.

RESULTS

A total of 37 articles reporting 40 HIV-positive patients with cardiac tamponade were included. These patients mainly experienced dyspnea, fever, chest pain, and cough. They were mostly presented with abnormal vital signs, such as tachypnea, tachycardia, fever, and hypotension. Physical examination predominantly revealed elevated Jugular venous pressure (JVP), muffled heart sounds, and palsus paradoxus. Echocardiography mostly indicated pericardial effusion, right ventricular collapse, and right atrial collapse. Most patients underwent pericardiocentesis, while others underwent thoracotomy, pericardiotomy, and pericardiostomy. Furthermore, infections and malignancies were the most common etiologies of cardiac tamponade in HIV-positive patients, respectively. Eventually, 80.55% of the patients survived, while the rest expired.

CONCLUSION

Infections and malignancies are the most common causes of cardiac tamponade in HIV-positive patients. If these patients demonstrate clinical manifestations of cardiac tamponade, clinicians should conduct echocardiography to diagnose it promptly. They should also undergo pericardial fluid drainage and receive additional therapy, depending on the etiology, to reduce the mortality rate.
