Hypertension 2002: An Overview 1
Leading Risks For Death (World Health Organization 1995) 2
What Is Blood Pressure? Ø Blood pressure is the amount of force on the walls of the arteries as the blood circulates around the body. 3
What Do The Numbers Mean? Ø The upper number is when the heart beats (Systolic Blood Pressure SBP) Ø The lower number is when the heart relaxes (Diastolic Blood Pressure DBP) 4
Measured in mm Hg (millimeters of mercury) e. g. 124/82 mm Hg § Systolic=124 mm Hg § Diastolic= 82 mm Hg 5
What is Hypertension ? It is also called High Blood Pressure (HBP) 140 Hypertension is a blood pressure of 140/90 mm Hg or greater 6 90
Classification of Blood Pressure for Adults Blood pressure category 7 Blood pressure (mm. Hg) Diastolic Systolic Optimal <120 and <80 Normal High normal <130 130– 139 and or <85 85– 89 Hypertension Stage 1 Stage 2 Stage 3 140– 159 160– 179 >180 or or or 90– 99 100– 109 >110
What Causes HYPERTENSION ? Ø 95% ‘not known’ § Genetics 40% § Environment 60% (lifestyle) Ø 5% underlying disease 8
Your Lifestyle is Related to Hypertension Ø Sedentary lifestyle Ø Unhealthy diet § To little fresh fruit, fresh vegetables and low fat dairy products § To much salt (sodium) and saturated fats Ø Being overweight Ø Alcohol Ø Stress 9
Hypertension Is More Common in Older People 10
22% of Adult Canadians Have Hypertension Treated and controlled Unaware of their hypertension 16% 42% 19% Not treated and not controlled 23% Treated and not controlled 11
Untreated Hypertension Cause Atherosclerosis Strokes Dementia Heart failure Kidney failure Poor circulation – impotence, leg cramps when walking Ø Premature death Ø Ø Ø Re 12 Pressure related damage Ø Strokes Ø Heart failure Ø Kidney failure Ø Confusion Ø Premature death
Why Do Some Develop Heart Disease or Stroke and Others Don’t? Ø There are several risks that cause heart attacks and strokes Ø The more risks and the higher the risks, the greater the chance of developing heart disease or stroke Ø More than 9 in 10 Canadians with hypertension have other risks of developing heart disease and stroke 13
Cardiovascular Risks Ø High blood pressure Ø Smoking Ø High cholesterol Ø Diabetes Ø Low physical activity Ø Stress Ø Obesity Ø Diet Ø Excess alcohol consumption 14
What Are the Benefits of Treating Hypertension? For a decrease of 10/5 mm Hg: Ø Heart attack by 15% Ø Heart failure by 50% Ø Stroke by 38% 15 Ø Death by 10%
Who Can Help You Control & Treat Your Hypertension ? Ø Your family Ø Family doctor Ø Nurse, dietitian, pharmacist, psychologist, exercise physiologist Ø Medical specialist 16
How Low Should Your Blood Pressure Be Lowered to? Ø Most people: § Less than 140/90 mm Hg when measured at the doctors office § Less than 135/85 mm Hg when measured at home Ø Diabetes or kidney disease § Less than 130/80 mm Hg when measured at the doctor’s office 17
9 Ways to Help Control Hypertension 18 Ø Eat a healthy diet Ø Be active for at least 45 -60 minutes 4 -5 times / week Ø Control your weight Ø Limit daily alcohol to 2 drinks/day or less

Drugs for Hypertension 20
Antihypertensive Drugs (Drugs Used to Treat Hypertension) Ø risk of death and disability Ø Usually do not make you feel better Ø Usually do not make you feel worse Ø Usually need to be combined to normalize blood pressure 21
Antihypertensive Drugs (Cont. ) Ø Are taken for life unless your doctor stops the medication Ø Need to be continued, even though you feel well Ø Can interact with alcohol 22
Classes of Drugs ØDiuretics ØBeta-Blockers ØACE inhibitors ØCalcium channel blockers ØAngiotensin receptor blockers (ARB’s) ØAlpha blockers ØMiscellaneous 23
