From the Guidelines
I strongly advise against attempting to practice as an Intensive Care Unit (ICU) doctor without formal medical education and training, as it can lead to significant morbidity, mortality, and decreased quality of life for patients. Becoming qualified to work in an ICU requires years of formal medical education, including medical school (typically 4 years), internal medicine residency (3 years), and often cardiology fellowship training (3+ years), followed by specialized critical care training 1. This extensive education includes supervised clinical experience, hands-on procedural training, certification exams, and licensing requirements that cannot be substituted with informal instruction. Critical cardiac care involves managing life-threatening conditions like acute myocardial infarction, cardiogenic shock, and lethal arrhythmias, where proper training is essential for patient safety.
Some key aspects of cardiology training for ICU practice include:
- Cardiopulmonary physiology, especially as it applies to cardiac patients in the ICU setting 1
- Use of bedside cardiac ultrasonography to assess preload responsiveness, left ventricular systolic and diastolic function, and other critical cardiac conditions 1
- Training in intensive care, including management of acute coronary syndromes, ST-elevation myocardial infarction, cardiogenic shock, and other life-threatening conditions 1
Pursuing formal medical education through accredited institutions and following the established pathway to becoming a qualified cardiac critical care physician is the only recommended course of action. Medication administration in this setting (such as vasopressors, inotropes, antiarrhythmics, and thrombolytics) requires precise dosing and monitoring that comes from formal training. If you're interested in this field, I recommend following the established pathway to becoming a qualified cardiac critical care physician, as outlined in the guidelines for training in adult cardiovascular medicine 1 and task force 1: training in clinical cardiology 1.

From the Research
Cardiology in Intensive Care Unit (ICU) Setting
To practice as an ICU doctor, it is essential to have a strong foundation in cardiology, particularly in critical care cardiology. The evolution of critical care cardiology has led to the development of comprehensive cardiac intensive care units designed to care for the sickest patients with cardiovascular disease 2.
Key Concepts in Cardiology for ICU Doctors
Some key concepts in cardiology that ICU doctors should be familiar with include:
- The use of positive pressure ventilation (PPV) in the cardiac intensive care unit, including its indications, potential cardiopulmonary interactions, and complications 3
- The application of cardiovascular physiology to the critically ill patient, including the use of ventricular pressure-volume relationship and time-varying elastance model to understand cardiovascular physiology and pathophysiology 4
- The management of life-threatening cardiovascular diseases and comorbid conditions that require advanced critical care in an intensive care unit 2
Training and Education for ICU Doctors
ICU doctors should receive comprehensive training in critical care medicine, including cardiology, to provide state-of-the-art clinical care to critically ill patients 5. The training should encompass all disciplines that provide care in the intensive care unit and all levels of training, from medical students through all levels of postgraduate training and continuing medical education 5. The World Federation of Societies of Intensive and Critical Care Medicine has set up a task force to address issues concerning the training, functions, roles, and responsibilities of an ICU specialist 6.
Skills and Knowledge Required for ICU Doctors
ICU doctors should acquire and maintain the skills necessary to provide compassionate and ethical care to critically ill patients, including:
- Understanding of the underlying cardiac and pulmonary pathophysiology
- Proficiency with the indications, appropriate selection, potential cardiopulmonary interactions, and complications of PPV
- Ability to interpret advanced hemodynamic monitoring and illustrate the physiologic basis and hemodynamic effects of therapeutic interventions 4
