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
What is the primary role of chest CT angiography in evaluating a patient with suspected cor pulmonale?
To assess right ventricular function noninvasively
To rule out pulmonary embolism as a cause of pulmonary hypertension
To directly measure pulmonary arterial pressure
To identify interstitial fibrosis in detail
Ventilation/perfusion (V/Q) scanning is especially useful in diagnosing:
Idiopathic pulmonary arterial hypertension
Cor pulmonale due to sarcoidosis
Cor pulmonale caused by chronic thromboembolic pulmonary hypertension (CTEPH)
Acute cor pulmonale from severe asthma
Which of the following is a common systemic complication of right heart failure in cor pulmonale?
Pulmonary edema
Hyponatremia
Hepatomegaly and ascites
Hemorrhagic stroke
A holosystolic murmur heard best at the left lower sternal border in a patient with cor pulmonale most likely indicates:
Mitral regurgitation
Pulmonary stenosis
Tricuspid regurgitation
Atrial septal defect
What is the primary therapeutic goal of using diuretics in patients with cor pulmonale?
To treat bronchoconstriction in obstructive lung disease
To enhance right ventricular contractility
To reduce elevated right ventricular filling volumes
To lower systemic vascular resistance
