Instructions: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: The majority of acute coronary syndromes are caused by plaque ruptures. Proteases secreted by macrophages play an important role in plaque ruptures by degrading extracellular matrix proteins in the fibrous cap. Matrix metalloproteinases have been shown to be markers for cardiovascular disease whereas the members of the cathepsin protease family are less studied.', 'Cathepsin D, cathepsin L and cystatin B were measured in plasma at baseline from 384 individuals who developed coronary events (CEs), and from 409 age-matched and sex-matched controls from the Malmo Diet and Cancer cardiovascular cohort.', 'Cathepsin D (180 (142-238) vs 163 (128-210), p<0.001), cathepsin L (55 (44-73) vs 52 (43-67), p<0.05) and cystatin B levels (45 (36-57) vs 42 (33-52), p<0.001) were significantly increased in CE cases compared to controls. In addition, increased cathepsin D (220 (165-313) vs 167 (133-211), p<0.001), cathepsin L (61 (46-80) vs 53 (43-68), p<0.05) and cystatin B (46 (38-58) vs 43 (34-54), p<0.05) were associated with prevalent diabetes. Furthermore, cathepsin D and cystatin B were increased in smokers. The HRs for incident CE comparing the highest to the lowest tertile(s) of cathepsin D and cystatin B were 1.34 (95% CI 1.02 to 1.75) and 1.26 (95% CI 1.01 to 1.57), respectively, after adjusting for age, sex, low-density lipoprotein/high-density lipoprotein ratio, triglycerides, body mass index, hypertension and glucose, but these associations did not remain significant after further addition of smoking to the model. In addition, cathepsin D was increased in incident CE cases among smokers after adjusting for cardiovascular risk factors.
Output:
Are high levels of cathepsin D and cystatin B associated with increased risk of coronary events?
