#1
Which of the following is a common symptom of cardiac disease?
Chest pain
ExplanationOften indicative of myocardial ischemia or infarction.
#2
Which of the following is a risk factor for developing cardiac diseases?
High blood pressure
ExplanationIncreases the workload on the heart and can lead to hypertensive heart disease.
#3
Which of the following is a symptom of heart failure?
Edema
ExplanationOften presents as swelling in the legs, ankles, or abdomen due to fluid retention.
#4
Which of the following enzymes is commonly elevated in blood during a heart attack?
Creatinine kinase
ExplanationRelease occurs due to myocardial cell damage, aiding in the diagnosis of acute myocardial infarction.
#5
Which of the following is a common symptom of angina?
Chest pressure or discomfort
ExplanationOften triggered by physical or emotional stress and relieved by rest or medications like nitroglycerin.
#6
Which imaging technique is commonly used for the diagnosis of cardiac issues?
Ultrasound
ExplanationProvides real-time images of the heart's structure and function.
#7
Which of the following is a primary diagnostic tool for assessing cardiac function?
Echocardiogram
ExplanationUtilizes sound waves to create images of the heart's chambers and valves.
#8
What term refers to a condition where there is an abnormal heart rhythm?
Arrhythmia
ExplanationCan manifest as tachycardia, bradycardia, or irregular heartbeats.
#9
Which cardiac condition is characterized by the buildup of plaque in the arteries?
Atherosclerosis
ExplanationCan lead to coronary artery disease and increase the risk of heart attack and stroke.
#10
What is the medical term for a heart attack?
Myocardial infarction
ExplanationOccurs when blood flow to a part of the heart is blocked for a prolonged period, leading to tissue damage.
#11
Which of the following tests is typically used to assess the electrical activity of the heart?
Electrocardiogram (ECG/EKG)
ExplanationRecords the heart's electrical impulses, aiding in the diagnosis of arrhythmias and ischemic heart disease.
#12
What is the term for the abnormal enlargement of the heart?
Hypertrophy
ExplanationMay result from conditions like hypertension or valvular heart disease.
#13
What is the primary function of the pericardium?
To protect and lubricate the heart
ExplanationA double-layered sac that surrounds and protects the heart, reducing friction with surrounding structures.
#14
Which hormone increases heart rate and blood pressure during times of stress?
Adrenaline (epinephrine)
ExplanationReleased by the adrenal glands, preparing the body for 'fight or flight' response.
#15
Which of the following is a congenital heart defect characterized by a hole in the heart's septum?
Ventricular septal defect
ExplanationMay lead to abnormal blood flow between the heart chambers and cause symptoms like heart murmur or cyanosis.
