If one assumes an average rate of contraction of 75 contractions per minute, a human heart would contract approximately 108,000 times in one day, more than 39 million times in one year, and nearly 3 billion times during a 75-year lifespan. Each of the major pumping chambers of the heart ejects approximately 70 mL blood per contraction in a resting adult. This would be equal to 5.25 liters of fluid per minute and approximately 14,000 liters per day.

It covers the clinical manifestations, diagnostics, and laboratory values associated with MI. Nursing care, both immediate and post-recovery, is detailed alongside evaluating care efficacy and patient response to medical therapies. The impact of socio-demographic factors on coronary heart disease prevalence is also discussed.

It explains how these structures function together to maintain cardiovascular health. Key concepts like cardiac output, stroke volume, preload, and afterload are defined, with emphasis on their roles in the heart's mechanical and physiological processes.
