What is the common cause of infective carditis?

Fungus

Virus

Bacterium

Ricksettsiae

Answer and Explanation

The Correct Answer is C

A. Fungus: While fungal infections can cause infective endocarditis, they are much less common compared to bacterial infections. Fungal endocarditis typically occurs in immunocompromised individuals or those with specific risk factors.

B. Virus: Viral infections can affect the heart, but they are not a common cause of infective endocarditis. Most cases of endocarditis are associated with bacterial infections rather than viral ones.

C. Bacterium: The most common cause of infective endocarditis is bacterial infection. Bacteria, particularly Staphylococcus aureus, Streptococcus viridans, and Enterococcus, are frequently implicated in this condition. These bacteria can enter the bloodstream and adhere to heart valves or damaged cardiac tissue, leading to infection and inflammation.

D. Rickettsiae: Rickettsial infections are caused by a specific type of bacteria that are typically transmitted through arthropod vectors, such as ticks. While they can cause various illnesses, they are not a common cause of infective endocarditis.

Correct Answer is ["B","C","D"]

Explanation

A. Percutaneous coronary intervention: Percutaneous coronary intervention (PCI) is a treatment used to open blocked coronary arteries during a myocardial infarction but is not a complication of the event itself. It is a therapeutic procedure aimed at restoring blood flow and is not a direct consequence of myocardial infarction.

B. Sudden death: Sudden death can occur as a complication of myocardial infarction due to severe dysrhythmias or cardiac arrest resulting from electrical instability in the heart. This complication is critical and can occur shortly after the onset of an MI or during recovery.

C. Dysrhythmias: Dysrhythmias are common complications following myocardial infarction, often arising from ischemic damage to the heart muscle, which disrupts the normal electrical conduction pathways. These irregular heartbeats can range from benign to life-threatening.

D. Congestive heart failure: Congestive heart failure can develop as a complication of myocardial infarction due to the loss of functional cardiac muscle, resulting in decreased cardiac output and the heart's inability to pump effectively. This complication can develop acutely or progressively over time following an MI.

A. Carotid wall thinness B. Chronic kidney disease C. Coronary artery calcification D. Markers of inflammation, ischemia, and thrombosis

Correct Answer is A

Explanation

A. Carotid wall thinness: Carotid wall thinness is not considered a nontraditional risk factor for coronary artery disease (CAD). Traditional risk factors for CAD include age, gender, hypertension, hyperlipidemia, and smoking, while carotid wall thickness (rather than thinness) is often used as a marker for atherosclerosis and cardiovascular risk.

B. Chronic kidney disease: Chronic kidney disease (CKD) is recognized as a nontraditional risk factor for coronary artery disease. It is associated with increased cardiovascular risk due to factors like inflammation, mineral metabolism disorders, and increased vascular stiffness.

C. Coronary artery calcification: Coronary artery calcification is considered a nontraditional risk factor for CAD. It reflects the presence of atherosclerosis and is associated with an increased risk of cardiovascular events.

D. Markers of inflammation, ischemia, and thrombosis: Markers of inflammation (such as C-reactive protein), ischemia, and thrombosis (such as fibrinogen and D-dimer) are nontraditional risk factors for coronary artery disease. Elevated levels of these markers indicate increased cardiovascular risk and are used in risk stratification.
