Cardiovascular Physiology

Cardiovascular Physiology forms the backbone of understanding cardiac function, circulation, and hemodynamics. This session provides a comprehensive exploration of how the heart, vessels, autonomic nervous system, and microcirculation interact to maintain perfusion and respond to stress. As clinicians seek deeper foundational knowledge through a structured cardiology conference, this session links fundamental physiologic concepts with real-world clinical scenarios.

Participants will revisit pressure–volume loops, cardiac output dynamics, vascular resistance, microvascular autoregulation, and neurohormonal responses. Case discussions highlight how physiological principles explain shock states, exercise intolerance, arrhythmogenesis, valvular gradients, and heart failure mechanics. Attendees will understand how preload, afterload, contractility, and compliance shape symptoms and guide management.

A major emphasis is clinical integration of cardiac physiology principles into diagnostic reasoning. Examples include interpreting hemodynamic tracings, correlating physiology with imaging, understanding murmurs and Doppler findings, and predicting responses to therapy. The session also addresses physiology in special conditions—pregnancy, aging, congenital lesions, pulmonary hypertension, and athletic hearts.

The session concludes by examining modern techniques such as invasive pressure–volume analysis, right heart catheterization, cardiopulmonary exercise testing, autonomic assessment, and microvascular function testing. By the end, participants will have strengthened their ability to apply physiology to complex patient care.

Core Components of Cardiovascular Physiology

Cardiac Pump Mechanics

  • Understanding systolic and diastolic function using pressure–volume relationships.
  • Predicting clinical consequences of impaired contractility or compliance.

Vascular and Microcirculatory Function

  • Exploring determinants of blood pressure, resistance, and endothelial function.
  • Recognizing how microvascular dysfunction contributes to symptoms and risk.

Autonomic and Neurohormonal Regulation

  • Assessing sympathetic and parasympathetic influences on heart rate and contractility.
  • Linking hormonal pathways to heart failure and shock states.

Integrated Response to Stressors

  • Studying physiological changes during exercise, pregnancy, fever, or volume shifts.
  • Applying insights to personalized treatment and monitoring.
