Practice questions
- Which statement best reflects the cardiovascular safety of nicotine-containing products, including e-cigarettes?
- A proposed mechanism by which nicotine-containing products can promote vascular dysfunction is:
- A patient switches from combustible cigarettes to a non-combustible nicotine product. Which interpretation is most consistent with current evidence summarized in the review?
- Which conclusion about human cardiovascular evidence for newer nicotine-delivery products is best supported?
- A patient with metabolic dysfunction-associated steatotic liver disease (MASLD) asks whether the condition is relevant to cardiovascular assessment. Which response is best supported?
- Among the features of MASLD, which is identified in the reviewed evidence as an important modifier of cardiovascular risk?
- Which group of mechanisms is most consistent with proposed links between MASLD and atherosclerotic cardiovascular disease?
- An observational cohort finds more cardiovascular events among people with MASLD, even after adjustment for traditional risk factors. Which interpretation is most appropriate?
- A patient taking hydroxychloroquine for many years develops otherwise unexplained cardiac dysfunction. Which uncommon toxicity described in the literature should be considered?
- Which combination of cardiac adverse effects is associated with hydroxychloroquine in the reviewed literature?
- Which patient has the greatest set of risk factors for hydroxychloroquine-associated cardiac toxicity according to the reviewed evidence?
- Which statement best describes the overall cardiovascular profile of hydroxychloroquine in patients with autoimmune disease?
- In the proposed framework linking repeated exercise training to mitochondrial quality control, which signaling axis is emphasized?
- Which set contains the four mitochondrial quality-control modules coordinated in the exercise framework described in the review?
- Which interpretation best reflects the evidence strength for the proposed cardiovascular effects of exercise-mediated mitochondrial quality control?
- Which sequence most closely characterizes ferroptosis as summarized in the cardiovascular review?
- Which molecules are termed the “yellow players” in the reviewed discussion of the heme oxygenase–biliverdin reductase system?
- A researcher proposes manipulating bilirubin-related pathways to prevent cardiovascular ferroptosis. Which conclusion is most appropriate from the reviewed evidence?
- SLC12A-family cation-coupled chloride cotransporters are relevant to cardiac physiology primarily because they help regulate intracellular:
- A defect in potassium-handling cation-coupled chloride cotransporters could increase arrhythmia susceptibility by disrupting:
- According to the review of SLC12A transporters, how might chloride-transport abnormalities worsen ischemic myocardial injury?
- Which ion-current adaptation is described as helping preserve cardiac excitability during deep hibernation at low temperatures?
- How is blood flow redistributed in hibernating mammals, according to the reviewed evidence?
- A review of cardiovascular function during torpor reports that hibernators avoid severe cold-induced cardiac electrical instability. Which combination best matches the proposed adaptations?
- A researcher generalizes cardiovascular mechanisms of hibernation to humans. Which qualification is most appropriate based on the reviewed evidence?
