What is the trigger for angina pectoris?

A. Dilated: Dilated cardiomyopathy is characterized by an enlarged heart with decreased contractility and thinning of the ventricular walls. It does not involve disproportionate thickening of the interventricular septum.

B. Dystrophic: Dystrophic cardiomyopathy refers to muscle degeneration due to underlying muscular dystrophies. It does not specifically describe the thickening of the interventricular septum and is not a primary classification of cardiomyopathy.

C. Hypertrophic: Hypertrophic cardiomyopathy is marked by a disproportionate thickening of the interventricular septum, leading to impaired diastolic filling and potential obstruction of blood flow out of the left ventricle. This characteristic thickening is a hallmark of this condition.

D. Restrictive: Restrictive cardiomyopathy involves stiffening of the heart muscle, which impairs filling during diastole but does not specifically feature disproportionate thickening of the interventricular septum. Instead, it may present with normal or slightly thickened walls but with decreased compliance.

A. A woman presenting with malaise, lethargy, and copious nasal secretions: These symptoms are more indicative of a common cold or viral upper respiratory infection. While nasal secretions can occur in rhinosinusitis, the absence of facial pain or pressure suggests a cold rather than sinus involvement.

B. A man with a dry, stuffy nasopharynx, a sore throat, and temperature of 98.9°F: This presentation is typical of a common cold or upper respiratory infection. The symptoms of a dry, stuffy nasopharynx and sore throat are not specifically indicative of rhinosinusitis, which usually involves more pronounced nasal and facial symptoms.

C. A man complaining of general fatigue, a headache, and facial pain with a temperature of 100.9°F: This combination of symptoms strongly suggests rhinosinusitis. The presence of facial pain, headache, and fever indicates inflammation and infection of the sinuses, which is characteristic of rhinosinusitis rather than a common cold.

D. A woman complaining of generalized aches and who has a hoarse voice and reddened, painful upper airways: These symptoms align more closely with a viral upper respiratory infection or laryngitis. The absence of specific sinus-related symptoms such as facial pain or nasal obstruction makes rhinosinusitis less likely in this case.
