Describe how good management can improve both aspects Explain how the cardiovascular system adapts to exercise por Hannah Barton 1 How can stable angina progress to unstable angina (acute coronary syndrome) 2 How is blood pressure calculated? 3 How is reperfusion therapy useful in MI? 4 What is increased contractility of the heart a result of? 5 What is coronary artery disease an umbrella term for? 6 Aspirin for secondary prevention can reduce risk of MI, stroke or vascular death by how much…? 7 Why are blood pressure changes minimal during exercise? 8 Why must splenic contraction increase during exercise? 9 How can stable and unstable angina be differentiated from the history? 10 What is increased preload a result of? 11 What are some risk factors for the acute coronary syndromes? 12 What is variant angina? 13 How many patients experiencing an acute MI die before reaching the hospital? Reduces infarct size and can help to prevent death from heart failure and ventricular arrhythmias Up to 30% of RBCs are stored here and so increased contraction ejects more of these into blood stream to transport oxygen Ageing, hypertension, hypercholesteremia, smoking, obesity Cardiac output x systemic vascular resistance 25% Reduced pulmonary and systemic vascular resistance to blood flow Increased use of skeletal muscle pumps and peripheral vasoconstriction means Whether or not they are provoked by exercise 33% Conditions involving atherosclerosis restricting blood flow to the heart, causing ischaemia The plaque narrowing the lumen ruptures causing platelet aggregation, thrombus formation and unopposed vasoconstriction Angina without the presence of physical plaques; caused by intense vasospasm Increased sympathetic nervous system activity
