Which set correctly lists the four main heart valves?
3.
A clinician wants to distinguish stable angina from myocardial infarction in a patient with chest pain. Which finding most strongly favors infarction?
4.

5.
An infarct involving the apex and anterior interventricular septum is being discussed in a viva. Which coronary territory is most relevant?
6.
A patient with recurrent angina is advised to place nitroglycerin under the tongue during an acute attack. What is the main pharmacokinetic advantage of this route?
7.
Which adverse effect is most important to remember with ranolazine?
8.
A patient develops exertional angina during tachycardia. Which anatomical-physiological fact explains worsening ischemia in the left ventricle?
9.
Which calcium channel blocker is mainly a vascular smooth muscle vasodilator and is commonly used for angina with hypertension?
10.
A man has angina at rest due to coronary spasm. Which long-term preventive drug class is most appropriate?
11.
Which condition is included in the clinical spectrum of ischemic heart disease?
12.
A patient with exertional angina and hypertension is prescribed amlodipine. Which effect is most expected from this drug?
13.
A patient with angina and reduced ventricular systolic function is being considered for antianginal therapy. Which drug group requires caution because it may worsen heart failure and AV block?
14.
A patient with predictable exertional angina is started on a drug that lowers heart rate and myocardial contractility. Which drug best matches this therapeutic goal?
15.
A patient with stable angina develops marked dizziness and collapse after taking nitroglycerin with a drug for erectile dysfunction. Which mechanism best explains this event?
16.
A smoker develops severe chest pain at rest during early morning. ECG during pain shows transient ST elevation, but angiography later shows no fixed obstruction. What is the most likely mechanism?
17.
A patient develops ischemia involving the anterior wall of the left ventricle and anterior part of the interventricular septum. Which coronary branch is most likely involved?
18.
A student identifies a valve specimen with three cusps and no chordae tendineae at the right ventricular outflow. Which valve is most likely shown?
19.
A coronary plaque causes stable narrowing of the lumen. Which clinical and laboratory combination best fits this pathology?
20.
A man develops chest tightness while walking uphill. Pain settles within minutes after rest. ECG during exercise shows ST depression, while serum troponin is normal. What is the most likely diagnosis?
21.
A patient with chronic angina receives ranolazine. Which adverse effect is most important for examination and clinical safety?
22.
Which drug group is especially useful in vasospastic angina because it relaxes coronary vascular smooth muscle?
23.
Sublingual nitroglycerin relieves an acute anginal episode mainly by which action?
24.
A patient with coronary artery disease is counseled about prevention of worsening ischemic heart disease. Which intervention best targets disease progression rather than immediate pain relief?
25.
What is the main rationale for using β-adrenergic blockers in chronic stable angina?
26.
Which pair of heart valves is attached to chordae tendineae and papillary muscles?
27.
Which gross anatomical feature best differentiates atrioventricular valves from semilunar valves?
28.
A patient with persistent chronic angina has low blood pressure, limiting further dose increase of nitrates and β-blockers. Which drug may be added because it has little effect on heart rate and blood pressure?
29.
A patient has recurrent chest pain at rest, especially early morning. Coronary angiography between attacks is normal. Which mechanism best explains the symptoms?
30.
A man with chronic stable angina has chest pain only when climbing stairs. At rest he is asymptomatic. Which concept best explains this pattern?
31.
A patient with severe chest pain has raised troponin after prolonged coronary ischemia. Which tissue change best explains the biomarker rise?
32.
A patient has exertional chest discomfort that settles with rest. Troponin remains normal. Which pathological explanation best accounts for the normal biomarker level?
33.
A patient has brief chest pain during exertion that settles with rest. Troponin is normal. Which statement best explains this process?
34.
A patient with angina has severe bradycardia and AV block. Which antianginal drug group should be used with caution because it can worsen these conduction problems?
35.
A patient using a transdermal nitrate patch daily reports reduced benefit over time. Which approach helps reduce this problem?
36.
A patient using sildenafil for erectile dysfunction is prescribed nitroglycerin for angina. Which serious adverse effect is most likely if both are taken together?
37.
During an exercise stress test, a patient develops chest discomfort with horizontal ST-segment depression. Which process does this finding suggest?
38.
A patient with angina is given an organic nitrate. Which sequence correctly links its action to symptom relief?
39.
Which feature most strongly supports chronic stable angina?
40.
A patient on short-acting dihydropyridine therapy develops headache, flushing, ankle edema and palpitations. Which mechanism best explains the palpitations?
