BLOOD PRESSURE AND CHOLESTEROL THE BEGINNING OF YOUR END! Billy S. Arant, Jr., M.D., FASH Professor Emeritus, UTCOM-Chattanooga ASH Specialist in Clinical Hypertension Diplomate, American Board of Clinical Lipidology VASCULAR DISEASE—JUST THE FACTS • 70 % of US deaths due to heart attack, stroke, heart failure and aneurysm--all vascular problems! • ALL diabetics develop vascular disease and most are fat! • Vascular disease causes serious long-term disability! • Annual expenditures for vascular diseases of all causes exceed total costs of war in Iraq RUN FROM THE CURE! ARE YOU AT RISK? BEYOND YOUR CONTROL • • • • • • • Age Gender Race Heredity Prior cardiovascular event [Vascular abnormality] [Congenital heart defect] STROKEBELT WD Hall, AHA 1999 WITHIN YOUR CONTROL • • • • • • • Blood pressure Lipids Weight [waist] Blood sugar Tobacco Drugs Hormones ELEVATED BLOOD PRESSURE earliest indication of trouble • • • • Normal is below 120/80 mmHg at any age BP >115/75 is earliest indicator of vascular risk Systolic (top #) most reliable indicator of risk Every drug that lowers BP may not reduce but actually increase risk • Drugs that raise BP increase risk • Lowering BP to normal with proven drugs reduces risk Impact of High-Normal Blood Pressure on the Risk of Cardiovascular Disease Women Hi-Normal Hi-Normal Hazar d Ratio 2. 5 (n = 1794) 130 – 139/ 85 – 89 Normal Optimal Time, years *P < 0.001 for trend across categories.

DRUGS DRUGS CAN INCREASE RISK • Recreational drug use – Amphetamines, cocaine • Decongestants increase BP – Pseudophedrine • Hormones: estrogen, testosterone • NSAID’s [ibuprofen,naproxen,celebrex] – – – – 15,000 deaths/yr to GI bleeding Raise BP Reduces kidney function Reverses aspirin benefit to prevent blood clots PROSTAGLANDINS [inhibition] • Mediators of inflammation [reduces pain/retards healing] • Vasodilators to regulate organ blood flow [VC] – HTN, AMI/angina, CVA, CHF, ARF [intravascular volume] • Alters renal functions – RBF, GFR, loop NaCl, AVP/water in CD • GI mucus production to protect mucosa [bleed] READ PI/LABEL! REGARD TORT POTENTIAL! IBUPROFEN PRECAUTIONS • OTC – no longer than 3 days for fever • Allergy to NSAID including ASA • DO NOT take aspirin or acetaminophen w/ ibuprofen unless MD tells you to • DO NOT take if fluid intake is unreliable • Hx heart liver GI or renal disease, HBP, stroke • Pregnant, plans or breast feeding • Surgery planned • If taking warfarin, ß-blockers, CYA, digoxin, diuretics, lithium, metotrexate, phenytoin • DO NOT drive or operate machinery until… • NO alcohol w/ ibuprofen OTHER FACTORS your doctor may not be measuring • Uric acid [gout, stones] – – – – < 6 mg/dl Stroke risk increased when values higher Seems to facilitate cholesterol build up Risk equivalent to heart attack Rx- ↓production or ↑excretion • Homocysteine [dementia] < 9 mg/dl – Stroke risk increased when values higher – Treatment with folic acid and B₁₂ high dose • C-reactive protein [CRP] < 1 mg/dl – indicates vascular inflammation and risk of a cardiovascular event • Kidney function [eGFR] >60 ml/min/1.73m² – Reduced kidney function increases CV risk – Hypertension destroys kidneys [20% dialysis patients] ISCHEMIC STROKE V.

KNOW YOUR NUMBERS don’t leave it to your doctor • BP <120/80 + treatment – drugs that affect angiotensin [ACEi or ARB] • Cholesterol to goal for your specific risk – – – – – – • • • • • • high HDL reduces risk >50 F; >40 M low LDL reduces risk <100 no risk; <80 DM, <70 prior CVE non-HDL (TC – HDL) is total bad cholesterol <130 no risk, <100 w/ risk triglycerides <150 but lower is better don’t wait for diet and exercise alone to work statins proven to reduce risk independent of LDL Fasting blood sugar <100 (A1C <6.0) + DM Waist <33” F; <37” M CRP < 1.0 Uric acid < 6.0 Homocysteine < 9.0 Kidney function [eGFR] > 60 Treat the problems you have with outcome-proven drugs • • • • • • Blood pressure – include ACEi or ARB Statin Niacin Omega 3 ‘s Anticoagulant – aspirin, coumadin Antiarrhythmic- beta blocker HOW TO LOSE WEIGHT works every time! • Know what you’re eating—read the label! • Eat less – Maintain normal weight m-1800 kcal, f-1500 kcal – Lose weight reduce calories by > 300 kcal/day – portion control • Eat healthy – Protein: fish, eggs, less meat, low fat dairy, beans – Fat: no trans, less saturated, more olive or canola oil – Carbs: fresh fruits, no juices, colored vegetables + cauliflower, whole grain bread or cereal, no high fructose corn sugar ever, use sugar substitutes – Adkins, South Beach, Sugar Busters are healthy • Exercise more – 30 minutes 3 times a day to start, then daily (walking will burn 1.25 lb fat/month • Sleep 8 hours every night HOW TO FAIL LONG-TERM WEIGHT LOSS! • Choose anything other than what’s on the previous slide • Try advertised products for diet or exercise • Buy something sold in doctor’s office or with some doctor’s name on it • Get your advice from Dr. Feelgood • Believe everything the nutritionist tells you ANTIDOTE TO VASCULAR EVENT reducing your risk • • • • • • • • • • • Can you afford to survive? Family history of vascular disease? Have you had vascular screening? What about your weight/waist? Do you have erectile dysfunction? Do you abuse tobacco? Do you exercise regularly? Do you take an aspirin daily? Do you take any drug that raises BP? Still taking hormones? Do you know your numbers? WHAT TO DO? if you think you’re having a heart attack or stroke • Chew and swallow 325 mg aspirin • Call 911 • Ask to be taken to a certified Heart or Stroke Center Plan ahead – Determine the heart or stroke center closest to you – Ask if a neurologist who is a stroke specialist will be available to you – Clot busters and Merci retriever to remove blood clots – Confirm that door to cath lab time is <60 minutes HOW TO IMPROVE YOUR CHANCES OF ACTUALLY HAVING A VASCULAR EVENT? • • • • • • • • • • • • • • • • • • Ignore symptoms or signs Have a previous TIA, stroke or heart attack Ignore your blood pressure or skip your medicine to save money Have a sibling or parent with cerebral aneurysm at young age Don’t take blood thinners for atrial fibrillation Treat your diabetes by diet and exercise Smoke, chew or dip liberally Weight no problem as long as you don’t look fat Lower your cholesterol by diet and exercise only Don’t take daily aspirin >40 yrs of age Don’t have vascular screening >50 years of age Take NSAID for pain and decongestants for cold/sinus problem Get off the hormones—embrace menapause Be blood kin to someone who has vascular disease Active sex life with uncontrolled high blood pressure Be black Live in the Southeastern USA Avoid certified heart or stroke centers MOST VASCULAR EVENTS ARE PREVENTABLE !
