Coexistence of Colorectal Adenomas and Coronary Calcification in Asymptomatic Men and Women

Yun KE, Chang Y, Rampal S, Zhang Y, Cho J, Jung HS, et al.

J Clin Gastroenterol, 2018 07;52(6):508-514.
PMID: 28471937 DOI: 10.1097/MCG.0000000000000824

GOALS: Because of shared risk factors between clinically manifest cardiovascular disease and colorectal cancer, we hypothesized the coexistence of subclinical atherosclerosis measured by coronary artery calcium (CAC) and colorectal adenoma (CRA) and that these 2 processes would also share common risk factors.
BACKGROUND: No study has directly compared the risk factors associated with subclinical coronary atherosclerosis and CRA.
STUDY: This was a cross-sectional study using multinomial logistic regression analysis of 4859 adults who participated in a health screening examination (2010 to 2011; analysis 2014 to 2015). CAC scores were categorized as 0, 1 to 100, or >100. Colonoscopy results were categorized as absent, low-risk, or high-risk CRA.
RESULTS: The prevalence of CAC>0, CAC 1 to 100 and >100 was 13.0%, 11.0%, and 2.0%, respectively. The prevalence of any CRA, low-risk CRA, and high-risk CRA was 15.1%, 13.0%, and 2.1%, respectively. The adjusted odds ratios (95% confidence interval) for CAC>0 comparing participants with low-risk and high-risk CRA with those without any CRA were 1.35 (1.06-1.71) and 2.09 (1.29-3.39), respectively. Similarly, the adjusted odds ratios (95% confidence interval) for any CRA comparing participants with CAC 1 to 100 and CAC>100 with those with no CAC were 1.26 (1.00-1.6) and 2.07 (1.31-3.26), respectively. Age, smoking, diabetes, and family history of CRC were significantly associated with both conditions.
CONCLUSIONS: We observed a graded association between CAC and CRA in apparently healthy individuals. The coexistence of both conditions further emphasizes the need for more evidence of comprehensive approaches to screening and the need to consider the impact of the high risk of coexisting disease in individuals with CAC or CRA, instead of piecemeal approaches restricted to the detection of each disease independently.

Fulltext Severe left anterior descending artery stenosis with proximal arteriovenous malformation presenting as acute myocardial infarction

Oteh M, Azarisman SM, Hanim NM, Noorfaizan S

Singapore Med J, 2009 Feb;50(2):e76-8.
PMID: 19296018

Congenital coronary artery anomalies are rare, with an incidence of about 0.06-1.3 percent of all patients undergoing cardiac catheterisation. They are commonly asymptomatic, but potentially serious lesions may lead to myocardial ischaemia, infarction and/or sudden cardiac death. The occurrence of a concomitant stenotic lesion is exceedingly rare. We report an 80-year-old man who presented with acute anterior myocardial infarction. Coronary angiography revealed severe proximal left anterior descending (LAD) and arteriovenous malformation (AVM) from the first septal branch of the LAD. The LAD stenosis and the AVM were successfully treated with two Jomed covered stents.

Subclinical coronary artery disease in Asian rheumatoid arthritis patients who were in remission: a pilot study

Ma NH, Teh CL, Rapaee A, Lau KB, Fong AY, Hi S, et al.

Int J Rheum Dis, 2010 Aug;13(3):223-9.
PMID: 20704618 DOI: 10.1111/j.1756-185X.2010.01533.x

INTRODUCTION: Rheumatoid arthritis (RA) patients who have active disease with longer disease duration have been reported to have increased risk of cardiovascular events compared to the normal population.
OBJECTIVE: The primary aim of our study is to ascertain the prevalence of significant asymptomatic coronary artery disease (CAD) in Asian RA patients who are in remission using multi-detector computed tomography (MDCT). The secondary aims of our study are the usage of pulse wave velocity and the biomarkers N-terminal pro-brain natriuretic peptide (NT-proBNP) and high-senstivity C-reactive protein (hs-CRP) to detect subclinical atherosclerosis in RA patients.
METHODS: We performed a comparative cross-sectional study of 47 RA patients who were in remission with a control group of non-RA patients with a history of atypical chest pain in Sarawak General Hospital from November 2008 to February 2009. All patients underwent 64-slice MDCT, assessment of arterial stiffness using the SphygmoCor test and blood analysis for NT-proBNP and hsCRP.
RESULTS: There were 94 patients in our study with a mean age of 50 +/- 8.8 years. The RA and control patients in each group were matched in terms of traditional CV risk factors. Our RA patients had a median disease duration of 3 years (IQR 5.5). MDCT showed evidence of CAD in nine (19.1%) RA patients and three (6.4%) control patients (P = 0.06). There was no significant association between pulse wave velocity (PWV) and presence of CAD in our RA group. There was no significant correlation between PWV with levels of proBNP or hsCRP in our RA patients.
CONCLUSIONS: In our current pilot study with the limitation of small sample size, RA was not associated with an increased risk of CAD in our RA patients who were in remission. Larger studies of CAD in Asian RA patients are needed to confirm our current finding.

Brachial-ankle pulse wave velocity is associated with coronary calcium in young and middle-aged asymptomatic adults: The Kangbuk Samsung Health Study

Cainzos-Achirica M, Rampal S, Chang Y, Ryu S, Zhang Y, Zhao D, et al.

Atherosclerosis, 2015 Aug;241(2):350-6.
PMID: 26071657 DOI: 10.1016/j.atherosclerosis.2015.05.031

OBJECTIVE: To evaluate the association between brachial-ankle pulse wave velocity (baPWV), a convenient, non-radiating, readily available measurement of arterial stiffness, and coronary artery calcium (CAC), a reliable marker of coronary atherosclerosis, in a large sample of young and middle-aged asymptomatic adults; and to assess the incremental value of baPWV for detecting prevalent CAC beyond traditional risk factors.
METHODS: Cross-sectional study of 15,185 asymptomatic Korean adults who voluntarily underwent a comprehensive health screening program including measurement of baPWV and CAC. BaPWV was measured using an oscillometric method with cuffs placed on both arms and ankles. CAC burden was assessed using a multi-detector CT scan and scored following Agatston's method.
RESULTS: The prevalence of CAC > 0 and CAC > 100 increased across baPWV quintiles. The multivariable-adjusted odds ratios (95% CI) for CAC > 0 comparing baPWV quintiles 2-5 versus quintile 1 were 1.06 (0.87-1.30), 1.24 (1.02-1.50), 1.39 (1.15-1.69) and 1.60 (1.31-1.96), respectively (P trend < 0.001). Similarly, the relative prevalence ratios for CAC > 100 were 1.30 (0.74-2.26), 1.59 (0.93-2.71), 1.74 (1.03-2.94) and 2.59 (1.54-4.36), respectively (P trend < 0.001). For CAC > 100, the area under the ROC curve for baPWV alone was 0.71 (0.68-0.74), and the addition of baPWV to traditional risk factors significantly improved the discrimination and calibration of models for detecting prevalent CAC > 0 and CAC > 100.
CONCLUSIONS: BaPWV was independently associated with the presence and severity of CAC in a large sample of young and middle-aged asymptomatic adults. BaPWV may be a valuable tool for identifying apparently low-risk individuals with increased burden of coronary atherosclerosis.

Egg consumption and coronary artery calcification in asymptomatic men and women

Choi Y, Chang Y, Lee JE, Chun S, Cho J, Sung E, et al.

Atherosclerosis, 2015 Aug;241(2):305-12.
PMID: 26062990 DOI: 10.1016/j.atherosclerosis.2015.05.036

OBJECTIVE:
The association of egg consumption with subclinical coronary atherosclerosis remains unknown. Our aim was to examine the association between egg consumption and prevalence of coronary artery calcium (CAC).
METHODS:
Cross-sectional study of 23,417 asymptomatic adult men and women without a history of cardiovascular disease (CVD) or hypercholesterolemia, who underwent a health screening examination including cardiac computed tomography for CAC scoring and completed a validated food frequency questionnaire at the Kangbuk Samsung Hospital Total Healthcare Centers, South Korea (March 2011-April 2013).
RESULTS:
The prevalence of detectable CAC (CAC score > 0) was 11.2%. In multivariable-adjusted models, CAC score ratio (95% confidence interval [CI]) comparing participants eating ≥ 7 eggs/wk to those eating < 1 egg/wk was 1.80 (1.14-2.83; P for trend = 0.003). The multivariable CAC score ratio (95% CI) associated with an increase in consumption of 1 egg/day was 1.54 (1.11-2.14). The positive association seemed to be more pronounced among participants with low vegetable intake (P for interaction = 0.02) and those with high BMI (P for interaction = 0.05). The association was attenuated and no longer significant after further adjustment for dietary cholesterol.
CONCLUSION:
Egg consumption was associated with an increased prevalence of subclinical coronary atherosclerosis and with a greater degree of coronary calcification in asymptomatic Korean adults, which may be mediated by dietary cholesterol. The association was particularly pronounced among individuals with low vegetable intake and those with high BMI.
