Heart at Hand: The Role of Point-of-Care Cardiac Ultrasound in Internal Medicine.

Bedside echocardiography stands as a cornerstone diagnostic tool in internal medicine, offering rapid, real-time evaluation of cardiac structure and function across a wide spectrum of acute and chronic conditions. Its application, particularly when combined with lung and inferior vena cava (IVC) ultrasound, significantly enhances diagnostic accuracy for fluid balance assessment, dyspnea, and hypotensive states, guiding timely therapeutic decisions. Focused cardiac ultrasound (FoCUS) enables internists to assess left ventricular function, right atrial pressure, valvular abnormalities, and pericardial effusion, facilitating differentiation between cardiac and non-cardiac causes of symptoms such as dyspnea, chest pain, and hemodynamic instability. While operator-dependent, echocardiography can be effectively integrated into internal medicine practice through structured training programs that combine theoretical knowledge with supervised hands-on experience. This integration enhances clinical decision-making, optimizes patient management, and reduces the need for immediate specialist consultation. Widespread adoption of focused ultrasound techniques in internal medicine wards promises not only improved patient outcomes but also more efficient utilization of healthcare resources. Continued education and institutional support are fundamental to embedding echocardiography into routine care, ensuring internists are equipped to leverage this powerful bedside modality. This narrative review aims to underscore the transformative impact of bedside echocardiography in internal medicine, demonstrating its capacity, when combined with lung and IVC ultrasound, to optimize diagnostic pathways and treatment decisions across diverse acute and chronic settings.
