Cor Pulmonale - Quiz

Which of the following noninvasive tools is typically used first to assess right ventricular structure and function in suspected cor pulmonale?

• Right heart catheterization

• Electrocardiography

• Chest CT angiography

• Echocardiography

Which of the following is considered the gold standard for diagnosing pulmonary hypertension in cor pulmonale?

• Transthoracic echocardiography

• CT pulmonary angiography

• Right heart catheterization

• Chest radiograph

How does right ventricular failure in cor pulmonale typically affect left ventricular function?

• Increases LV preload due to backflow from RV

• Decreases LV filling due to leftward septal shift

• Enhances LV contractility through compensatory hypertrophy

• Causes mitral regurgitation from annular dilation

Which of the following symptoms is most commonly reported in patients with cor pulmonale?

• Chest pain at rest

• Palpitations

• Dyspnea on exertion

• Productive cough with hemoptysis

Which of the following is a classic physical exam finding in chronic cor pulmonale?

• Loud S1

• Loud P2 (pulmonary component of S2)

• Diastolic murmur at apex

• Splitting of S1

A chest radiograph in a patient with cor pulmonale is most likely to reveal:

• Left atrial enlargement

• Right atrial and right ventricular dilation

• Pulmonary edema

• Cardiomegaly with pericardial effusion

Which echocardiographic feature is most consistent with chronic cor pulmonale?

• Enlarged left atrium

• Septal flattening in systole

• Dilated and hypertrophied right ventricle

• Increased ejection fraction

What parameter measured during right heart catheterization confirms the presence of pulmonary hypertension?

• Mean pulmonary artery pressure (mPAP) ≥ 25 mmHg at rest

• Right atrial pressure < 5 mmHg

• Left ventricular end-diastolic pressure > 20 mmHg

• Cardiac output > 8 L/min

Which of the following is the primary goal in the treatment of cor pulmonale?

• Eradication of pulmonary emboli

• Prevention of arrhythmias

• Treatment of the underlying pulmonary condition

• Administration of ACE inhibitors

Which of the following is the most common cause of cor pulmonale worldwide?

A.

• Pulmonary embolism
  

• Interstitial lung disease

• Chronic obstructive pulmonary disease (COPD)

• Obstructive sleep apnea
