Summary This video provides a lecture on the causes of heart failure, specifically focusing on left-sided and right-sided heart failure. The causes are categorized into three categories: afterload, contractility, and preload. Afterload causes on the left side include systemic hypertension and aortic valve stenosis, while on the right side, it is caused by pulmonary hypertension, often due to COPD or pulmonary embolus. Contractility causes include myocardial infarction, myopathies, pericarditis, and tamponade. Preload causes on the left side include increased fluid (hypervolemia) and regurgitation of the mitral and aortic valves, while on the right side, it includes increased fluid, regurgitation of the tricuspid and pulmonary valves, and tricuspid stenosis. The video concludes by summarizing the common causes of heart failure and how they fit into these categories. Highlights - The video explains the causes of heart failure, focusing on left-sided and right-sided heart failure. - Afterload causes on the left side include systemic hypertension and aortic valve stenosis. - Afterload causes on the right side include pulmonary hypertension, often due to COPD or pulmonary embolus. - Contractility causes of heart failure include myocardial infarction, myopathies, pericarditis, and tamponade. - Preload causes on the left side include increased fluid (hypervolemia) and regurgitation of the mitral and aortic valves. - Preload causes on the right side include increased fluid, regurgitation of the tricuspid and pulmonary valves, and tricuspid stenosis. - The video concludes by summarizing the common causes of heart failure and how they fit into the categories of afterload, contractility, and preload.

I came here on KZbin because I was looking to see how TMAO in the bloodstream causes heartfailure. I was looking to see how dietary choices work into this. Thanks.
