HEART DISEASE WHY WE GET THEM AND WHAT TO DO ABOUT THEM SOMNATH KUMAR CONSULTANT CARDIOLOGIST Department of Cardiology LANCASHIRE TEACHING HOSPITALS UNITED KINGDOM
The Problem…. Cardiovascular disease continues to be the biggest killer in the UK today Almost 200,000 deaths per year One in three premature deaths Half of these CHD A quarter stroke Most can be prevented/delayed
Objectives Prevention: Primary versus Secondary Coronary Artery Disease (CHD) Risk Factors Q RISK 2 Risk Assessment Do You Know Your Numbers? AND your Pulse ? Q&A
INTER-HEART:52 Countries - every inhabited continent15,152 cases with14,820 control group • ”Disease” related risk factors • Diabetes • Hypertension • Abdominal obesity • ApoB/ApoA1 • Behaviour related risk factors Alcohol intake Exercise Psychosocial stress Current smoking

Physical activity If maintained BP can be reduced by 3.8 to 2.6 mmHg, systolic and diastolic 30 minutes - on five or more days/wk Reduces the risk of CHD by more than 18%, If no exercise is taken studies show that people are 30% more likely to become hypertensive.
Abdominal Obesity-KNOW YOUR FIGURES • BMI • Normal < 25 • Obese 25-29.9 • Obese > 30 • Waist circumference • > 40 inches in men • > 35 inches in women • Waist circumference is more sensitive of risk of heart attack than BMI
New Definition of High Blood Pressure • Old – BP a number to keep below 140/90 • New - a disease of the blood vessel where vascular biology is altered • Arteries cannot vasodilate properly and sodium and glucose accumulate in the arterial wall • New Goals 140 systolic / 90 diastolic • Lowers damage to heart brain, eyes, kidneys, pancreas, blood vessels of the legs/feet, sexual function
What is Cholesterol? • Cholesterol is used to form cell membranes • LDL (BAD) pro-inflammatory • High levels are a predictor of atherosclerosis and heart disease • HDL (GOOD) anti-inflammatory • Removes excess cholesterol from arteries • Slows the growth of plaques • High levels protect against heart attack • Low levels increase risk http://www.fundaciondiabetes.org/activ/prevenir_obesidad/images/obesidad.jpg
Cholesterol Management Guidelines Increase HDL Exercise Smoking Cessation Weight Reduction Questionable: Alcohol – Red Wine Estrogen • Lower LDL • < 7% saturated fat • 10-25 grams fiber • 2 grams plant stanols • like Take Control • Statins
Definition of Metabolic Syndrome Central obesity (waist circumference ≥ 94cm for European men and ≥ 80cms for European women) and any two of the four factors below: ↑ Trigs ≥ 1.7 mmol/L or treatment for this ↓ HDL < 1.03 mmol/L in men, < 1.29 mmol/L in women or specific treatment for this ↑ BP ≥130/85 or treatment of previously diagnosed hypertension ↑ FPG ≥ 5.6mmol/L or diagnosed T2 diabetes International Diabetes Federation, 2004
Alcohol intake Low to moderate intake is associated with a lower risk of CVD Heavy alcohol is associated with high risk for hypertension and stroke Drinkers of more than 35 units/wk double their risk of mortality Binge drinking strongly associated with a large rise in BP Women drinking more than ever before.
Red Flags • Blood pressure >160/100 mmHg Cholesterol >7.5 mmol/l
Smoking Strong association with CVD Smoking as few as 3 per/day doubles risk of MI or death Best quit success with counselling and pharmacological therapy Level of risk falls with abstinence
Stress Management INTERHEART Study confirmed that psychosocial factors can contribute to sudden cardiac death
Levels of risk <10% risk over the next 10 years - classed as low CVD risk 10-20% risk over the next 10 years - classed as moderately increased CVD risk >20% estimated risk over the next 10 years - classed as high risk.

Action Plan 1. Get a annual check-up, know your numbers and follow-up • Monitor your cholesterol and fasting blood glucose • BP targets vary according to patients • Check thyroid, liver and kidney function, Vitamin D levels, hormones 2. Examine your diet and get a nutrition assessment with a dietitian 3. Exercise Non-Negotiable daily appointment for you 30-60 minutes 5 days a week 4. Develop a management plan to control stress and anxiety and depression... and seek help if no improvement 5. Quit smoking 6. Learn to measure your own pulse – practice brings perfection
