Symptoms and Clinical Findings of Heart Disease in Pregnancy Flashcards
Which symptom in a pregnant woman is most suggestive of underlying heart disease rather than normal pregnancy changes?
A. Fatigue and exercise intolerance
B. Progressive dyspnea and orthopnea
C. Increased respiratory effort
D. Mild lower extremity edema
- B. Progressive dyspnea and orthopnea
- Rationale: While mild dyspnea is common in normal pregnancy due to increased oxygen demands, progressive dyspnea and orthopnea indicate pulmonary congestion or left-sided heart failure. These are hallmark signs of cardiac dysfunction, particularly mitral stenosis or left ventricular failure.
- Buzz Words: Pulmonary congestion, heart failure, orthopnea, progressive dyspnea.
A nocturnal cough in pregnancy is most likely indicative of:
A. Physiological changes of pregnancy
B. Pulmonary congestion or heart failure
C. Gastroesophageal reflux disease (GERD)
D. Asthma exacerbation
- B. Pulmonary congestion or heart failure
- Rationale: A nocturnal cough is a classic symptom of pulmonary edema or left ventricular dysfunction, distinguishing it from physiological dyspnea in pregnancy. This symptom reflects worsening pulmonary congestion during recumbency.
- Buzz Words: Pulmonary edema, left ventricular dysfunction, nocturnal cough.
Hemoptysis in pregnancy is most commonly associated with which of the following conditions?
A. Anemia
B. Pulmonary hypertension or mitral stenosis
C. Hyperemesis gravidarum
D. Lower respiratory tract infection
- B. Pulmonary hypertension or mitral stenosis
- Rationale: Hemoptysis is a red flag in pregnancy, often pointing to severe pulmonary hypertension, mitral stenosis, or pulmonary embolism. It requires immediate evaluation due to its life-threatening implications.
- Buzz Words: Pulmonary hypertension, mitral stenosis, hemoptysis, emergency evaluation.
A pregnant woman with syncope should be evaluated for:
A. Physiological anemia
B. Arrhythmias or severe stenosis
C. Orthostatic hypotension
D. Dehydration
- B. Arrhythmias or severe stenosis
- Rationale: Syncope associated with exertion in pregnancy suggests arrhythmias, aortic stenosis, or cardiomyopathy. Simple vasovagal syncope is more benign and not exertion-related.
- Buzz Words: Syncope, arrhythmias, aortic stenosis, cardiomyopathy, exertion.
Chest pain in pregnancy that raises concern for ischemia or aortic dissection is often associated with which of the following findings?
A. Physiological systolic murmur
B. Persistent tachycardia
C. Grade 3/6 systolic murmur or greater
D. Diastolic murmur
- D. Diastolic murmur
- Rationale: A diastolic murmur is always pathological, often linked to mitral stenosis or aortic insufficiency. When paired with chest pain, ischemia or aortic dissection must be ruled out, particularly in high-risk conditions like Marfan syndrome.
- Buzz Words: Diastolic murmur, mitral stenosis, aortic dissection, chest pain.
Cyanosis in a pregnant woman is most indicative of:
A. Chronic anemia
B. Congenital heart disease causing hypoxia
C. Pulmonary embolism
D. Physiological changes in oxygenation

- Rationale: Cyanosis indicates systemic hypoxia, commonly due to right-to-left cardiac shunting in cyanotic congenital heart diseases like Tetralogy of Fallot. This is a pathological finding requiring evaluation.
- Buzz Words: Cyanosis, congenital heart disease, right-to-left shunt, hypoxia.
Clubbing of the fingers in pregnancy is most often associated with:
A. Long-term hypoxia from congenital heart disease
B. Gestational diabetes
C. Physiological changes of pregnancy
D. Nutritional deficiencies
- A. Long-term hypoxia from congenital heart disease
- Rationale: Clubbing reflects chronic hypoxia, often caused by cyanotic congenital heart disease. It is not a physiological finding in pregnancy.
- Buzz Words: Clubbing, chronic hypoxia, congenital heart disease.
Persistent neck vein distention in pregnancy is suggestive of:
A. Pulmonary edema
B. Right-sided heart failure
C. Physiological venous engorgement
D. Superior vena cava syndrome

- Rationale: Persistent neck vein distention suggests right-sided heart failure or elevated central venous pressure (CVP). It may also be a sign of constrictive pericarditis or tricuspid regurgitation.
- Buzz Words: Neck vein distention, right-sided heart failure, elevated CVP.
Which murmur in pregnancy always warrants further evaluation?
A. Functional systolic murmur
B. Diastolic murmur
C. Grade 1/6 systolic murmur
D. Soft systolic murmur in late pregnancy
- B. Diastolic murmur
- Rationale: A diastolic murmur in pregnancy is always pathological and frequently indicates mitral stenosis or aortic insufficiency. This contrasts with functional systolic murmurs, which are benign.
- Buzz Words: Diastolic murmur, pathological, mitral stenosis.
Cardiomegaly in pregnancy is best detected using which diagnostic tool?
A. Electrocardiography (ECG)
B. Chest radiography
C. Cardiac MRI
D. Echocardiography
- D. Echocardiography
* Rationale: Echocardiography is the preferred diagnostic tool for detecting cardiomegaly, as it provides detailed imaging of ventricular enlargement, valve abnormalities, or pericardial effusion without radiation exposure.
* Buzz Words: Cardiomegaly, echocardiography, ventricular enlargement.
Which heart sound in pregnancy is most concerning for underlying heart disease?
A. Third heart sound (S3)
B. Fourth heart sound (S4)
C. Persistent split S2
D. Ejection click
- B. Fourth heart sound (S4)
* Rationale: A fourth heart sound (S4) is pathological and indicates reduced ventricular compliance, often seen in hypertensive heart disease or aortic stenosis. It is a concerning finding in pregnancy.
* Buzz Words: S4, ventricular compliance, aortic stenosis.
Which finding is most consistent with pulmonary hypertension in pregnancy?
A. Cyanosis
B. Persistent tachycardia
C. Elevated pulmonary artery pressures
D. Functional systolic murmur
- C. Elevated pulmonary artery pressures
* Rationale: Pulmonary hypertension in pregnancy is diagnosed when the pulmonary arterial pressure exceeds 25 mmHg at rest. This condition is commonly seen in congenital heart defects or mitral valve disease.
* Buzz Words: Pulmonary hypertension, elevated pressure >25 mmHg, congenital heart disease.
Which of the following is a misleading finding that can mimic heart disease in pregnancy?
A. Functional systolic murmur
B. Diastolic murmur
C. Cyanosis
D. Persistent tachycardia
- A. Functional systolic murmur
* Rationale: Functional systolic murmurs are common and benign in pregnancy due to increased cardiac output. They should not be confused with pathological murmurs, such as diastolic murmurs or loud systolic murmurs (≥3/6).
* Buzz Words: Functional systolic murmur, benign, increased cardiac output.
Lower extremity edema in pregnancy is typically:
A. Always pathological and suggests heart failure
B. A physiological finding unless accompanied by other symptoms of heart disease
C. Diagnostic of right-sided heart failure
D. Indicative of gestational hypertension
- B. A physiological finding unless accompanied by other symptoms of heart disease
* Rationale: Mild lower extremity edema is common in normal pregnancy due to venous stasis and compression by the gravid uterus. Generalized or severe edema may suggest heart failure.
* Buzz Words: Edema, venous stasis, physiological vs. pathological.
Which of the following symptoms differentiates pathological dyspnea from physiological changes in pregnancy?
A. Fatigue
B. Dyspnea with exertion
C. Orthopnea and progressive worsening
D. Increased respiratory rate

A grade 3/6 systolic murmur in a pregnant woman is:
A. Likely benign if unaccompanied by other findings
B. Always indicative of pathological changes
C. Suggestive of pulmonary hypertension

Which clinical finding in pregnancy suggests arrhythmias or significant cardiac pathology?
A. Persistent tachycardia with S4
B. Functional systolic murmur
C. Mild fatigue and exercise intolerance
D. Increased respiratory effort
- A. Persistent tachycardia with S4
* Rationale: Tachycardia is physiological in pregnancy, but persistent tachycardia combined with an S4 suggests significant cardiac pathology like arrhythmias or heart failure.
* Buzz Words: Tachycardia, S4, arrhythmias, cardiac pathology.
What symptom is most likely to be an early indicator of pulmonary congestion in pregnancy?
A. Hemoptysis
B. Nocturnal cough
C. Cyanosis
D. Syncope
- B. Nocturnal cough
* Rationale: A nocturnal cough is an early sign of pulmonary congestion, often due to left ventricular dysfunction or heart failure.

A. Right axis deviation
B. 15-degree left axis deviation
C. ST-segment elevation
D. Deep Q waves in lead I

What is a normal finding on ECG during pregnancy that should not raise concern?
A. Prolonged PR interval
B. Flattened T waves
C. Complete heart block
D. ST-segment depression in all leads
