Appropriate measures to decrease PTS-related burdens may include the prevention of DVT, clear diagnostic criteria for PTS, and an education campaign aimed at increased standardization in the management of DVT. Gaps in the current understanding of the risk factors, diagnostic criteria, preventive strategies, and even treatment modalities for PTS hamper the ability of clinicians to employ measures that could reduce the occurrence of this disorder and the associated morbidity.
This study is the first systematic review of risk factors for stroke in China and supports the importance of current public health initiatives to manage the risk factors appropriately to reduce risk of stroke in high risk patients. Additionally, this study has been co-authored by prominent Chinese and US physicians and researchers with expertise in cardiovascular disease, neurologic disorders, epidemiology, and real world data. While there have been several systematic reviews of real world associations of risk factors for coronary artery disease, none focus specifically on the population of China, where there is growing evidence that such risk factors are poorly treated or uncontrolled, especially in rural areas.BackgroundTo better understand the impact of traditional cardiovascular risk factors on risk of coronary artery disease (CAD) in China, a systematic review of all Chinese observational studies published in either English or Chinese in MEDLINE and EMBASE over the last 5 years was performed and the association between any of 5 traditional risk factors (ie, hypertension, diabetes, elevated lipid levels, obesity, and smoking) and the risk of CAD was studied.Methods and resultsThe study found a consistent relationship between lipid levels and CAD. Higher low-density lipoprotein cholesterol values were associated with greater risk of CAD, with an odds ratio as high as 3.31. Other factors found to be significant contributors to the risk of CAD included hypertension (crude odds ratio range of 1.40–5.11), diabetes (1.50–5.97), and smoking (1.37–5.19). An association between obesity and CAD in China was observed, but the evidence supporting this was considered weak due to the paucity of studies found as part of this review.ConclusionsThis review provides a systematic summary of CAD risk factors in China and demonstrates the important differences that exist in CAD risk factors between countries and regions. Approaches to reduce CAD globally must take into account the unique risk factors that drive CAD in each country and region as is demonstrated by these findings.
Average baseline triglyceride (TG) level was 269 mg/dL (SD 342 mg/dL); 91% had TG levels between 150 and 399 mg/dL. A total of 77% were overweight/obese, 23% had elevated blood pressure, 23% had a family history of high triglycerides, and 11% reported a psychiatric diagnosis (33.3% of those with severe TG elevations). Diet and activity change were the first-line therapies; few were taking lipid-lowering medications (baseline, 5.1%; follow-up, 11.4%). TG levels declined by 23% (average, 88 mg/dL; SD 231), often with a decline or plateau in TG risk category. Children with a lower body mass index (<85% gender- and age-matched percentile) were more likely to improve in TG category than heavier children (70% vs 40%; P ≤ .05).
Objectives: Body mass index (BMI) commonly is used in obesity classification as a surrogate measure, and obesity is associated with a cluster of risk factors for cardiovascular disease. The aim of this study was to investigate the impact of BMI on short-term outcomes after cardiac surgery.Design: A retrospective cohort study. Setting: University teaching hospital, 2 centers. Participants: The study comprised 4,740 patients who underwent cardiac surgery at 2 hospitals-from Interventions: No changes to standard practice were required.Measurements and Main Results: Patients were assigned into 6 BMI groups as follows: underweight (BMI o18.5 kg/ m 2 ), normal weight (Z18.5 to o25 kg/m 2 ), overweight (Z25 to o30 kg/m 2 ), class I obese (Z30 to o35 kg/m 2 ), class II obese (Z35 to o40 kg/m 2 ), and class III obese (BMI Z40 kg/ m 2 ). Short-term major postoperative complications (postoperative stroke, cardiac arrest, new atrial fibrillation/flutter, permanent rhythm device insertion, deep sternal infection, sepsis, prolonged ventilation, pneumonia, renal dialysis, renal failure, intensive care unit readmission, total intensive care unit hours, and readmission in 30 days, and mortalities (in-hospital mortality, 30-day mortality, surgical mortality) were compared among various BMI groups after cardiac surgery. Age, sex, surgery type, family history of coronary artery disease, diabetes, hypertension, heart failure, and lipid-lowering medication were the risk factors for early outcomes. Multiple logistic regression analysis indicated that the underweight and class III obese BMI groups demonstrated significant, adverse differences in some shortterm outcomes, including deep sternal infection, prolonged ventilation, new atrial fibrillation/flutter, and renal failure. However, being in the overweight or class I obese group demonstrated a positive effect on discharge and surgical mortality.Conclusions:The results of this study demonstrated that extreme obesity and underweight were significantly associated with early major adverse clinical outcomes. However, there was an "obese paradox" in short-term mortality after cardiac surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
