Q1
A 58-year-old man with ischemic cardiomyopathy presents with decompensated heart failure. Invasive hemodynamics reveal a cardiac index of 1.7 L/min/m², PCWP of 24 mmHg, and systemic vascular resistance (SVR) of 1800 dynes·sec·cm-5
Q2
Which of the following ECG criteria is most specific for diagnosing left ventricular hypertrophy (LVH) with strain pattern?
Q3
According to current guidelines, what is the primary indication for primary prophylactic ICD implantation in non-ischemic dilated cardiomyopathy?
Q4
In patients with severe aortic stenosis undergoing echocardiographic evaluation, what parameter defines high-gradient severe aortic stenosis?
Q5
Which cardiac biomarker exhibits the highest sensitivity and specificity for detecting acute myocardial injury within the first 3 hours of symptom onset?
Q6
In patients presenting with acute ST-elevation myocardial infarction (STEMI), what is the maximum recommended door-to-balloon time for primary PCI when performed at a PCI-capable center?
Q7
Which pharmacological class is established as first-line therapy for rate control in permanent atrial fibrillation with concomitant decompensated heart failure and reduced ejection fraction?
Q8
What is the hallmark hemodynamic finding on cardiac catheterization in a patient with constrictive pericarditis compared to restrictive cardiomyopathy?
Q9
Which genetic mutation is most commonly associated with familial hypertrophic cardiomyopathy (HCM)?
Q10
What is the primary mechanism of action of sacubitril when combined with valsartan in heart failure with reduced ejection fraction (HFrEF)?
Q11
In a patient with severe symptomatic mitral regurgitation due to posterior leaflet prolapse (Carpentier Type II) and prohibitive surgical risk, what is the preferred transcatheter intervention?
Q12
Which pharmacological agent is indicated for risk reduction of cardiovascular death and heart failure hospitalization in patients with symptomatic heart failure across the full spectrum of ejection fraction (including HFpEF)?
Q13
A 45-year-old competitive athlete experiences syncope during exertion. ECG shows deep T-wave inversions in the precordial leads and epsilon waves. Which diagnosis is most likely?
Q14
What is the primary hemodynamic consequence of an acute severe aortic regurgitation (e.g., secondary to infective endocarditis with leaflet perforation)?
Q15
Which antiplatelet agent is a direct, reversible, non-thienopyridine P2Y12 platelet receptor antagonist?
Q16
In adult congenital heart disease, what is the most common type of atrial septal defect (ASD)?
Q17
Which imaging modality is considered the gold standard for non-invasive tissue characterization, quantification of myocardial fibrosis (via late gadolinium enhancement), and accurate assessment of right and left ventricular volumes/ejection fraction?
Q18
What is the primary pathophysiological trigger for type 2 myocardial infarction (T2MI)?
Q19
Which medication is classified as a cardiac myosin inhibitor and has proven effective in reducing left ventricular outflow tract (LVOT) gradients and improving symptoms in symptomatic obstructive hypertrophic cardiomyopathy?
Q20
According to the Duke Criteria, which of the following represents a major diagnostic criterion for infective endocarditis?
Q22
What is the primary mechanism of action of PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitors like evolocumab?
Q23
Which physical examination finding is classically associated with cardiac tamponade (Beck’s Triad)?
Q24
In patients with severe symptomatic aortic stenosis and high surgical risk who undergo TAVR, what is the most common major vascular complication associated with transfemoral delivery systems?
Q25
Which advanced heart failure therapy utilizes a continuous-flow rotary pump mechanism to unload the left ventricle and propel blood into the ascending aorta, and what is the primary postoperative pharmacological management requirement regarding blood pressure?
