TSH levels
Match the type of heart failure with its characteristic manifestation:
Left-sided heart failure = Fluid may back up in the lungs, causing shortness of breath. Right-sided heart failure = Fluid may back up into the abdomen, legs and feet, causing swelling. Systolic heart failure = The left ventricle can't contract vigorously, indicating a pumping problem. Diastolic heart failure = The left ventricle can't relax or fill fully, indicating a filling problem.
Match the cause of heart failure with its associated condition:
Congenital HD = Volume overload lesions such as VSD, PDA are the most common causes of CHF in the first 6 months of life. Acquired Heart disease = Viral myocarditis, Acute rheumatic carditis, Rheumatic valvular heart disease. Idiopathic dilated cardiomyopathy = Doxorubicin cardiomyopathy, Cardiomyopathies associated with muscular dystrophies. Miscellaneous causes = Metabolic abnormalities, Severe hypoxia, Acidosis, Hypoglycemia, Hypocalcemia (newborns), Hyperthyroidism, SVT, Complete heart block, Severe anaemia, Bronchopulmonary dysplasia
Match the HF classification system with its respective stage:
New York Heart Association (NYHA) classification system = Class I: No limitation of physical activity; Class II: Slight limitation of physical activity; Class III: Marked limitation of physical activity; Class IV: Symptoms occur even at rest; discomfort with any physical activity. American College of Cardiology/American Heart Association (ACC/AHA) staging system = Stage A: High risk of heart failure but no structural heart disease or symptoms of heart failure; Stage B: Structural heart disease but no symptoms of heart failure; Stage C: Structural heart disease and symptoms of heart failure; Stage D: Refractory heart failure requiring specialized interventions.
Match the clinical manifestation with the age group it is commonly observed in:
In Infants = Poor feeding of recent onset; Tachypnoea; Poor weight gain; Cold sweat on the forehead. In older children = Shortness of breath; Easy fatiguability; Puffy eyelids; Swollen feet.
Match the physiological effect with its corresponding condition in causing congestive heart failure:
Metabolic abnormalities = Severe hypoxia; Acidosis; Hypoglycemia; Hypocalcemia (newborns) Hyperthyroidism = SVT; Complete heart block; Severe anaemia; Bronchopulmonary dysplasia
Match the following drugs used in the management of congestive heart failure with their mechanism of action:
Diuretics = Controls pulmonary and systemic venous congestion Inotropic agents = Increases the contractile state of the myocardium Afterload-reducing agents = Augment the stroke volume Vasodilators = Arteriolar vasodilators
Match the following signs and symptoms of heart failure with their corresponding clinical manifestation:
Tachycardia, gallop rhythm, weak and thready pulse = Compensatory responses to impaired cardiac function Tachypnoea, dyspnoea on exertion = Signs of pulmonary venous congestion Hepatomegaly, puffy eyelids, distended neck veins = Signs of systemic venous congestion Cardiomegaly on CXR = Almost always present in heart failure
Match the following investigations for congestive heart failure with their corresponding diagnostic purpose:
Chest radiograph = Confirmation of cardiomegaly Complete blood count (CBC) = Assessment of blood cell levels Urinalysis = Detection of urinary abnormalities 2-dimensional (2-D) echocardiography = Confirmation of chamber enlargement and impaired LV function
Match the following treatments for heart failure with their specific management purpose:
Elimination of underlying causes or correction of precipitating factors = Treatment consists of Control of heart failure – inotropes, diuretics, afterload reducing agents = General supportive measures Surgery when feasible (valvular disease) = Treatment of underlying causes or contributing factors Antihypertensive treatment for HBP = Management
Match the following drugs used in congestive heart failure with their specific recommended baseline test before administration:
Digitalis = Baseline ECG and electrolytes Beta-adrenergic blockers = Beneficial in chronic CHF Carnitine = In dilated cardiomyopathy Non-improvement with medical therapy within a few weeks to months is an indication = Cardiac transplantation
Match the following conditions with their respective surgical management approach:
Non improvement with medical therapy within a few weeks to months is an indication = Surgery may be palliative or corrective Cardiac transplantation is an option in progressively deteriorating cardiomyopathy = An indication for surgery when feasible Common cause of congestive heart failure in infants = Surgery when feasible (valvular disease) Congestive heart failure in newborns = Packed cell transfusion for anaemia
This quiz covers an introduction to congestive heart failure, including its clinical condition and types such as left-sided heart failure, right-sided heart failure, and systolic heart failure. Learn about the symptoms and effects of these different types of heart failure.
