Matching Pairs Week 1 CardiologyOnline version Describe the epidemiology of acute coronary syndromes and stable coronary artery disease Discuss the prognosis and impact of ischaemic heart disease on daily life. Describe how good management can improve both aspects Explain how the cardiovascular system adapts to exercise by Hannah Barton 1 How can stable angina progress to unstable angina (acute coronary syndrome) 2 What is increased preload a result of? 3 How is blood pressure calculated? 4 What are some risk factors for the acute coronary syndromes? 5 Why are blood pressure changes minimal during exercise? 6 How can stable and unstable angina be differentiated from the history? 7 How many patients experiencing an acute MI die before reaching the hospital? 8 Aspirin for secondary prevention can reduce risk of MI, stroke or vascular death by how much…? 9 Why must splenic contraction increase during exercise? 10 How is reperfusion therapy useful in MI? 11 What is increased contractility of the heart a result of? 12 What is coronary artery disease an umbrella term for? 13 What is variant angina? Increased use of skeletal muscle pumps and peripheral vasoconstriction means Reduced pulmonary and systemic vascular resistance to blood flow Increased sympathetic nervous system activity Conditions involving atherosclerosis restricting blood flow to the heart, causing ischaemia Whether or not they are provoked by exercise Ageing, hypertension, hypercholesteremia, smoking, obesity 25% 33% Cardiac output x systemic vascular resistance Up to 30% of RBCs are stored here and so increased contraction ejects more of these into blood stream to transport oxygen Reduces infarct size and can help to prevent death from heart failure and ventricular arrhythmias 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
