Hypertension

Introduction

Hypertension in the adult world is common and very familiar . In fact the incidence of the disease in men and women is , roughly speaking , 50 million Americans (______ , 2004 ) or 217 per 1000 . Furthermore , the prevalence rate is approximately one (1 ) in five (5 ) or 18 .38 or 50 million people in USA . There is also undiagnosed prevalence of hypertension : more than 15 million (more than 30 of 50 million are undiagnosed ) which means to say that more or less , approx 1 in 18 or 5 .51 or 15 [banner_entry_middle]

million people in USA

Statistics on the incidence of hypertension available worldwide , on the other hand , is estimated to be 600 million people affected worldwide (Cardiovascular Diseases – Prevention and Control , WHO , 2001-2002 . The age-adjusted prevalence of hypertension in overweight U .S . adults (BMI 25 and 30 ) is 23 .9 percent for men and 23 .0 percent for women compared with 18 .2 percent for men and 16 .5 percent for women who are not overweight (BMI 25 . The prevalence for obese adults (BMI 30 ) is 38 .4 percent for men and 32 .2 percent for women . High blood pressure does not mean excessive emotional tension , although emotional tension and stress can temporarily increase the blood pressure . An elevation of the systolic and /or diastolic blood pressure increases the risk of developing heart disease , kidney disease , hardening of the arteries , eye damage , and stroke . These complications of hypertension are often referred to as end-organ damage because damage to these organs is the end result of chronic (long duration ) high blood pressure . Accordingly the diagnosis of high blood pressure in an individual is important so that efforts can be made to normalize the blood pressure and , thereby prevent the complications . Since hypertension affects approximately 1 in 5 adults in the United States , it is clearly a major public health problem

I . Definition of terms

Hypertension is defined as mean systolic blood pressure 140 mm Hg , mean diastolic 90 mm Hg , or are currently taking antihypertensive medication (Ames , 1985 . Every time the heart beats , it pumps oxygen-rich blood through the blood vessels , or arteries , that run through the body . Blood pressure is the force of the blood pressing on against the walls of the arteries . Blood pressure is always given as two numbers , the systolic and diastolic pressures . Both are essential . Usually they are written one above or before the other — for example , 120 /80 mmHg . The top , or first , number is the systolic and the bottom , or second number , is the diastolic . If a person ‘s blood pressure is 120 /80 , that it is “120 over 80 ” The pressure of blood against the artery walls when the heart beats is called systolic pressure . The pressure between beats when the heart relaxes is called diastolic pressure

Nonfatal and fatal cardiovascular disease (CVD ) – including coronary heart disease (CHD ) and stroke , as well as renal disease , intensify increasingly with higher levels of both systolic (SBP ) and diastolic (DBP ) blood pressure levels . These… [banner_entry_footer]
