Progression Of Atherosclerosis

Background: Microalbuminuria (MA) is associated with an increased risk of cardiovascular disease (CVD) but the mechanism by which microalbuminuria imparts this increased risk is not known. In this study we assessed the relationship between MA and the development and progression of atherosclerosis by measuring the incidence of new CAC and the progression of existing CAC in individuals free of clinical CVD. Methods : The Multi-Ethnic Study of Atherosclerosis (MESA) is a prospective cohort study of 6,814 participants free of clinical CVD at entry who underwent assessment of coronary artery calcification (CAC) by computerized tomography at baseline. Overall, 6,775 individuals had data available on urinary albumin creatinine ratio (UACR); 1,109 individuals were excluded for missing data or macroalbuminuria (UACR≥300 mg/g). Incident CAC was defined as detectable CAC at follow-up among those with CAC=0 at baseline, and absolute CAC score change among those with CAC>0 at baseline. Relative risk (RR) regression adjusted for covariates; and multivariable adjusted median regression was employed to assess the independent relationship of MA with CAC incidence and progression. Results : Of the 5,666 subjects (mean age 62±10 years, 48% males), baseline MA was seen in 424 (7%) participants, who were more likely to have CAC compared to those with normal UACR (62% vs. 48%, p<0.0001). During a mean follow-up of 2.4±0.8 years, those with MA were more likely to develop CAC (28% vs. 15%, p<0.0001) and they had a higher absolute median increase in CAC (47 vs. 29 Agatston Units, p<0.0001). After adjustment for age, gender, ethnicity, site, follow-up duration, diabetes, hypertension, smoking, family history of heart attack, total cholesterol, lipid lowering medications and body mass index; MA was associated with incident CAC (RR 1.65; 95%CI 1.41–2.48) among those with CAC=0 at baseline. Among those with CAC>0 at baseline, MA was associated with a median increase in CAC of 7.93 (95%CI 0.38 –15.47) Agatston Units in multivariable adjusted analyses (variables noted above). Conclusion : MA is independently associated with development of incident CAC and progression of CAC in an asymptomatic multi-ethnic population, and may in part explain its associated increased risk of CVD.

Abstract Background : We aimed to characterize the independent predictors of systemic thromboembolism (ST) after left chamber thrombi. Methods: A retrospective analysis on the medical records of 175 patients diagnosed with left chamber thrombi by transthoracic echocardiography (TTE) at three centers were carried out. Multivariate logistic regression was performed to determine the relationship of each characteristic with ST. Multivariate Cox proportional survival analysis was conducted, with covariate adjustments, to identify predictors of all-cause mortality. Results: During a median 42 months of follow-up (25th–75th percentile: 20–62 months), 24 (13.7%) patients had ST, and 62 (35.4%) died. History of diabetes and thrombus mobility were independent predictors of ST (P = 0.003, P = 0.02, respectively). There was a significant association between abnormal ejection fraction (EF) and all-cause mortality (P = 0.003). Conclusions: The morbidity associated with ST and the increased risk for mortality associated with left chamber cardiac thrombi relates to medical history, thrombus state, and diminished heart function.

The association between the cumulative hypertension burden and the development of atrial fibrillation (AF) is unclear. We aimed to investigate the relationship between hypertension burden and the development of incident AF. Using the Korean National Health Insurance Service database, we identified 3 726 172 subjects who underwent 4 consecutive annual health checkups between 2009 and 2013, with no history of AF. During the median follow-up of 5.2 years, AF was newly diagnosed in 22 012 patients (0.59% of the total study population; 1.168 per 1000 person-years). Using the blood pressure (BP) values at each health checkup, we determined the burden of hypertension (systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg), stratified as 0 to 4 per the hypertension criteria. The subjects were grouped according to hypertension burden scale 1 to 4: 20% (n=742 806), 19% (n=704 623), 19% (n=713 258), 21% (n=766 204), and 21% (n=799 281). Compared with normal people, subjects with hypertension burdens of 1, 2, 3, and 4 were associated with an 8%, 18%, 26%, and 27% increased risk of incident AF, respectively. On semiquantitative analyses with further stratification of stage 1 (systolic BP of 130–139 mm Hg or diastolic BP of 80–89 mm Hg) and stage 2 (systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg) hypertension, the risk of AF increased with the hypertension burden by up to 71%. In this study, both a sustained exposure and the degree of increased BP were associated with an increased risk of incident AF. Tailored BP management should be emphasized to reduce the risk of AF.

The results of a field survey of herpes zoster over a period of 18 months are described and the difficulties of such a survey mentioned.A total of 246 patients with herpes zoster, only 16% of whom had attended hospital, is reported. It is calculated that the yearly incidence in the population was approximately 2 per 1000.Full investigation and ‘follow up’ was undertaken in 184 cases. These are classified according to the site of the zoster—the dorsal, supra-orbital and cervical regions being affected in almost 90%, the dorsal region alone accounting for 53·3%.Herpes generalisatus occurred in 7, or 38%, of the cases, recurrent herpes zoster in 6, or 3·3%, while there was one case of motor paralysis affecting lower limb.The majority of patients were apparently well at the onset of the zoster, but 27 had some associated disease; 5 gave a history of trauma prior to the onset and 2 were related to pregnancy.The seasonal and geographical distribution is given and, while the numbers are too small for statistical analysis, the disease in 1947 showed two peaks of higher incidence, the one in May and the other in October. Crowding or density of population did not appear to be important, and the disease occurred sporadically rather than in epidemic form.There was a higher proportion of female cases, but when related to the population as a whole no sex differentiation was observed. Of the patients 60% were over 45 years of age.There was no evidence that housing conditions or occupation were of aetiological significance or that the disease was more common among any particular section of the community.Eleven patients had been associated with other cases of herpes zoster before developing the disease, while 3 gave a suggestive history of prior contact with chickenpox.A condition indistinguishable from chickenpox occurred among the contacts of 10 patients, 12 individuals being affected, and there was one instance of concurrent herpes zoster and chickenpox. Other infections such as mumps, measles and rubella, while as common in association with the onset of herpes zoster, were not so frequently found as the chickenpox condition amongst contacts of the disease.The results of the survey as regards the relationship of chickenpox and herpes zoster are discussed. It is considered that the evidence does not favour a significant association with chickenpox prior to the onset of herpes zoster, but that the facts are consistent with the view that a condition indistinguishable from chickenpox may follow contact with herpes zoster. It is suggested, however, that this may be a generalized manifestation of the virus of zoster rather than true chickenpox.

Abstract Context.—Forensic pathologists regularly investigate the deaths of individuals with a history of drug abuse. Autopsy, including toxicology testing, reveals no cause for death in a subset of this cohort. Objective.—To determine whether deaths with an undetermined cause and manner of death are associated with a history of drug abuse. Design.—Retrospective matched case-control study of 52 decedents whose cause of death remained undetermined following autopsy, matched 1:2 to a control group of living patients admitted for cholecystectomy according to age and date of death or procedure. Results.—Individuals whose cause of death was undetermined were 5.3 times (95% confidence interval, 1.9– 14.5) more likely to have a history of drug abuse than were patients with cholecystitis. Conclusions.—Decedents with a history of chronic drug abuse appear to be at an increased risk of dying by their chronic drug abuse, even in the absence of any anatomical or toxicologic finding at autopsy to account for death.

Hydatid cyst of the adrenal gland (HCAG) is an exceptional occurrence. We report our experience of six cases of HCAG and discuss the diagnosis and treatment of this hydatid localization. We retrospectively reviewed and analyzed the clinical files of six patients admitted to our institution from January 1990 to December 2000 for HCAG. Patients varied in age from 24—59 years. They were five males and one female. One patient had a history of pulmonary hydatidosis treated surgically 10 years previously. Five patients presented with lumbar pain and one patient had bouts of hypertension, headache, and palpitation. Physical examination was normal except in one patient who was hypertensive. Preoperative diagnosis was highly suggested by ultrasonography. CT scan performed in all cases clearly showed the relationship of the cyst with adjacent organs. Serology tests were positive in two cases. One patient had elevated urine VMA and was operated on with the diagnosis of cystic phaeochromocytoma. All six patients were operated on and had either an adrenalectomy (two cases) or partial pericystectomy (four cases). In one case, partial pericystectomy was conducted through a retroperitoneal laparoscopic approach. The hydatid nature of the cyst was confirmed pathologically. All patients had a smooth postoperative course with no cystic recurrence on follow-up. The diagnosis of HCAG is based mainly on ultrasonography and CT scan. Surgery with either partial or total excision of the cyst, with or without preservation of the adrenal gland, is the treatment of choice.

Apparent treatment resistant hypertension (ATRH) is an important health concern in the U.S. affecting approximately 9% of all hypertensive adults and growing. However, long-term prognosis of those with ATRH remains to be fully investigated, especially with regard to the presence of differences by sex. Using data from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) we examined the relationship between ATRH and CVD and effect modification by sex. Subjects in ALLHAT were 55 years or older (N male = 13,597 and N female = 11,919) and were randomized to one of four antihypertensive medications for the purposes of the trial. We used Cox Proportional Hazard models and tested for interaction of sex through use of a multiplicative interaction term, stratified analyses, the Aalen Additive Hazards model, and joint effects. Missing blood pressure readings were imputed using multiple imputation as a sensitivity analysis. Due to the design of ALLHAT, ATRH was assessed at the year 2 follow-up visit and subjects were then followed for an additional 6 years (average follow-up 4.7 years) during this time there were 5,030 CVD events. Overall (N=25,516), ATRH was associated with an approximate 30% increased risk of CVD (HR 1.30, 95% CI 1.19 – 1.42) compared to those without ATRH. This risk was greater in women than in men (p interaction <.0001). In women, ATRH was associated with an approximate 62% increase in risk of CVD (HR 1.62, 95% CI 1.41 – 1.86) while in men, ATRH was associated with an approximate 13% increase in risk of CVD (HR 1.13, 95% CI 1.01 – 1.27). Sex was also a modifier of the relationship on the additive scale (p-value 0.003). ATRH is associated with an increased risk of developing CVD and women with ATRH were at a greater risk of developing CVD compared to men. These findings provide important insights into the complex relationship between ATRH and cardiovascular health, and suggest that women, in particular, may be a high-risk subgroup. Thus future studies should examine these differences to aid in development of targeted treatment and interventions which would have a significant public health benefit.

Background: Atrial fibrillation (AF) is the most common arrhythmia worldwide and has a complex association with exercise capacity. The relationship of atrial fibrillation with cardiorespiratory fitness (CRF) has not been previously investigated. Methods: Cardiorespiratory fitness, as assessed by maximal oxygen uptake (VO2max), was measured at baseline in 1,950 middle-aged men (mean 52.6 ± 5.1 years) from the Kuopio Ischaemic Heart Disease Study (KIHD). Results: During an average follow-up of 19.5 years, there were 305 incident AF cases (annual AF rate of 65.1/1000 person-years, 95% CI: 58.2 to 72.8). Overall a non-linear association was observed between CRF and incident atrial fibrillation. Rate of incident AF varied from 11.5 (95% CI: 9.4-14.0) for the first quartile of CRF, to 9.1 (95% CI: 7.4-11.2) for second quartile, 5.7 (95% CI: 4.4-7.4) for third quartile and 6.3 (95% CI: 5.0-8.0) for the fourth quartile respectively, Figure 1. Usual levels of CRF were non-linearly associated with AF risk, Figure 2. Age-adjusted HR comparing top versus bottom fourth of usual CRF levels was 0.67(95% CI: 0.48-0.95), which attenuated to 0.98 (95% CI: 0.66-1.43) upon further adjustment for several risk factors. These findings were comparable across age, body mass index, history of smoking, diabetes and cardiovascular disease status at baseline. Conclusions: Improved fitness as indicated by higher levels of CRF is protective of atrial fibrillation within an optimal range, beyond which the risk of atrial fibrillation rises again. Our findings are congruent with emerging data on the complex relationship between physical fitness and incident AF.

Background. The aim of this study is to explore the association between the number of childbirths and the progress of atherosclerosis among Chinese women with hypertension or diabetes. Methods. In total, 1159 Chinese parous women from a community longitudinal survey conducted in the communities of Shijingshan district, Beijing, China, were included in our study. They were divided into three groups according to the number of childbirths, and the change in pulse wave velocity (PWV) was as an indicator of the progression of atherosclerosis because the increased PWV reflected the more serious atherosclerosis. After 3 years, we conducted follow-up visits to the subjects. Logistical regression analyses were applied to investigate the relationship between the number of childbirths and the progression of atherosclerotic stiffness and a stratification analysis was performed for history of hypertension and diabetes. Results. After 3-year follow-up, among women with diabetes, the OR of women with 2 childbirths was significant [3.5 (95% confidence interval 1.5, 7.9)] in model I, [3.1 (95% confidence interval 1.3, 7.2)] in model II, and the OR of women with ≥3 childbirths was significant [4.4 (95% confidence interval 1.3, 14.5)] in model I, [4.1 (95% confidence interval 1.2, 14.3)] in model II. Among women with hypertension, the risk of the progress of atherosclerosis was not significant. Conclusion. The increasing number of childbirths is associated with the progression of atherosclerotic stiffness among Chinese women with diabetes, independent of a variety of confounding factors.

Background: There are limited data regarding the relationship between transport status and mortality in anuric continuous ambulatory peritoneal dialysis (CAPD) patients. Methods: According to the dialysate to plasma creatinine ratio (D/P Cr), 292 anuric CAPD patients were stratified to faster (D/P Cr ≥0.65) and slower transport groups (D/P Cr <0.65). The Cox proportional hazards models were used to evaluate the association of transport status with mortality. Results: During a median follow-up of 22.1 months, 24% patients died, 61.4% of them due to cardiovascular disease (CVD). Anuric patients with faster transport were associated with an increased risk of all-cause mortality (HR (95% CI) = 2.16 (1.09-4.26)), but not cardiovascular mortality, after adjustment for confounders. Faster transporters with pre-existing CVD had a greater risk for death compared to those without any history of CVD. Conclusion: Faster transporters were independently associated with high all-cause mortality in anuric CAPD patients. This association was strengthened in patients with pre-existing CVD.

Background: Diabetes is a well-known risk factor for dementia. Despite emerging evidence that higher glucose variability is associated with cognitive decline and hypoglycemia is associated with increased risk for dementia, few studies have investigated the relationship of lower fasting glucose and glucose variability with cognitive performance in the general population. Hypothesis: Diabetic and lower levels of fasting glucose and higher visit-to-visit glucose variability over 10 years are associated with worse cognitive performance. Methods: Participants in the Multi-Ethnic Study of Atherosclerosis (N = 4,591; mean age 69.7 ± 9.4 years) completed a cognitive assessment at Exam 5 including the Cognitive Abilities Screening Instrument (CASI), Digit Symbol Coding (DSC), and Digit Span (DS, Forward and Backward combined) tests measuring global cognitive performance, executive function/processing speed, and working memory, respectively. We defined fasting glucose categories as low (<80 mg/dL), normal (80-99 mg/dL), impaired (100-125 mg/dL), and diabetic (≥126 mg/dL). Participants with diabetes were included in the diabetic category. We examined the relationship of Exam 1 and Exam 5 fasting glucose categories and visit-to-visit glucose variability (coefficient of variation across Exams 1-5) to scores on the CASI (0-100), DSC (0-133), and DS (0-28). We report regression coefficients ( β [95% confidence limits]) from regression models adjusted for age, sex, race/ethnicity, education, income, cardiovascular risk factors, and APOE genotype. Results: Relative to normal glucose, participants with diabetic fasting glucose performed significantly worse on the CASI (Exam 1 β = -0.75 [-1.36, -0.15]; Exam 5 β = -0.30 [-0.83, 0.23]), DSC (Exam 1 β = -2.97 [-4.20, -1.74]; Exam 5 β = -1.26 [-2.34, -0.18]), and DS (Exam 1 β = -0.39 [-0.72, -0.07]; Exam 5 β = -0.29 [-0.58, -0.003]). In contrast, participants with low Exam 1 fasting glucose performed significantly better on the DSC (Exam 1 β = 1.55 [0.45, 2.65]) and similarly on the CASI and DS compared to those with normal fasting glucose. Adjusting for glucose lowering medication attenuated associations with the DSC and DS but not the CASI. Accounting for heterogeneity in the low glucose category by hypoglycemia (<70 mg/dL) did not significantly alter results. Higher visit-to-visit glucose variability from Exam 1 to Exam 5 was associated with worse performance on the CASI ( β = -0.36 [-0.60, -0.12]) and DSC ( β = -1.14 [-1.63, -0.65]). Associations were consistent across race and sex. Conclusions: Results support the hypothesis that hyperglycemia and higher glucose variability are associated with worse cognitive performance. Despite previous suggestion of a link between hypoglycemia and incident dementia, lower antecedent fasting glucose may be associated with better executive function/processing speed in this population-based sample.
