Cardiometabolic Syndrome in Elderly Women
Rachel McLaughlin PharmD candidate University of Georgia November 6, 2012
Metabolic Syndrome
ATP III defined a multiplex risk factor for cardiovascular disease (CVD) Abdominal obesity (increased waist circumference) Dyslipidemia (raised TGs and low HDL) Elevated blood pressure Insulin resistance +/- glucose intolerance Proinflammatory state (elevated CRP) Prothrombotic state (elevated plasma plasminogen activator inhbitor and prothrombin)
Metabolic Syndrome
Underlying CVD risk factors Obesity, physical inactivity, atherogenic diet Major risk factors Cigarette smoking, hypertension, high LDL, low HDL, family history of premature CHD, aging Emerging risk factors High TGs, small LDL particles, insulin resistance, glucose intolerance, proinflammatory state, prothrombotic state
Metabolic Syndrome
At least three of the following:
Metabolic Syndrome
Metabolic Syndrome
Increase in risk of CVD outcomes with increasing number of traits CVD is the primary clinical outcome, but MetS also increases risk for type 2 diabetes and susceptible to polycystic ovary disease, fatty liver, cholesterol gallstones, asthma, sleep disturbances and some cancers
Age- and sex-specific prevalence and ten-year risk for cardiovascular disease of all 16 risk factor combinations of the metabolic syndrome A cross-sectional study Cardiovascular Diabetology, August 2010
Methods
German Metabolic and Cardiovascular Risk Project (GEMCAS) data from 2005 35,869 participants Ages 18-99, 61% women Physicians recorded DM and CVD histories and assessed MetS risk factors according to a standardized assessment Analyzed all 16 combinations of MetS risk factors association with 10-year risk of fatal and nonfatal MI Calculated age-standardized prevalence rates to compare CV comorbidities prevalence with different combinations
Results
Results
Most frequent combination in both men and women: WC-BP-GL More frequent in women than men: WC-HDL-BP 10% vs 3% In women, the 8 combinations with highest prevalence all included BP and 5 out of 8 included WC
Results
PROCAM analysis of 10-year risk for MI Much higher in men than women Women without MetS: 1.2% ; with: 2.3% Highest risk combos for women: TG-HDL-BP-GL, WC-TG-HDL-BP, and all five traits combined ESC score: 10-year risk of fatal MI Women without MetS: 1.2% ; with: 1.8% Highest risk combos for women: TG-HDL-BP-GL, WC-TG-HDL-BP
Discussion
There was a substantial influence of age and gender on the prevalence of combinations Every GL combo more prevalent in elderly Higher rates of WC in women Each combination of MetS may not uniformly increase CV risk HDL and BP frequent in high risk groups Treat these as higher risk factors than the others??
Body composition and its association with cardiometabolic risk factors in the elderly: A focus on sarcopenic obesity
Archives of Gerontology and Geriatrics: September 2012
Methods
2943 Korean subjects 60 years or older Body composition categorized into four groups: sarcopenic obese, sarcopenic nonobese, nonsarcopenic obese, and nonsarcopenic nonobese Sarcopenia = appendicular skeletal muscle mass divided by weight <1 SD below the mean for young adults Obesity = BMI >25 kg/m2 Measured cardiometabolic risk factors BP, glucose intolerance, lipid profiles, inflammatory markers, vitamin D level
Results
Sarcopenic obese group had most insulin resistance, metabolic syndrome, and CVD risk factors Lowest HDL and vitamin D levels in the sarcopenic obese group BP, glucose, lipid profiles -risk factors for CVD significantly associated with the obese subjects
Discussion
Skeletal muscle is a primary tissue responsible for insulin-mediated glucose disposal so muscle loss causes diminished glucose disposal High fat mass secretes proinflammatory adipocytokines We need to focus on both obesity and muscle loss
What do we do?
Obesity ATP III recommends tackling this first: lowers cholesterol, raises HDL, lowers blood pressure and glucose Lose 10% of body weight Reinforce with physical activity... help with sarcopenia Insulin resistance Blood pressure Lipids Several drugs will also lower CRP levels
For women, especially look at waist circumference, low HDL, high triglycerides and blood pressure as these caused the highest CV risk in elderly women As people age, look carefully for signs of insulin resistance and treat appropriately Exercise!
