EWARN weekly summary| 2nd to 8th February 2014

FOCUS ON: HIGH BLOOD PRESSURE (HYPERTENSION)

KEY FACTS  Worldwide, it is estimated that high blood pressure causes 51% of deaths due to stroke and 45% due to heart disease  Hypertension is a major risk factor for cardiovascular disease. Metabolic risk factors such as diabetes, high blood cholesterol and obesity, increase the risk of complications from high blood pressure, including heart disease, stroke, kidney failure and blindness  Treating hypertension results in a 40% decrease in the risk of stroke and 15% decrease in risk of MI

SIGNS AND SYMPTOMS  Hypertension is referred to as the “silent killer” since most individuals do not manifest symptoms  Hypertension is defined as a blood pressure: ≥140 systolic /90 diastolic (or ≥130 or ≥80 among people with diabetes or renal disease)

WHO IS AT RISK?  Certain behaviors and lifestyle choices are risk factors for hypertension and cardiovascular disease (in “Prevention” below)  Proportion of people with hypertension increases with age: 1 in 10 people in their 20s -30s; 5 in 10 people in their 50s  In the Western Pacific Region (WPR), 37% of adults older than 24 have high blood pressure  In the , 25% of adults 21 years old and above have high blood pressure

HYPERTENSION REPORTED IN TYPHOON YOLANDA Overall there have been over 14,000 consultations for hypertension in these areas. The following charts and tables show information from SPEED consultations in select typhoon-affected areas (Regions VI and VIII) from 10 Nov 2013 – 8 Feb 2014. Results shown are dependent upon facility reporting which varied over time. REGION VI In Region VI, there have been 3,829 consultations for hypertension reported through SPEED, mostly from the Capiz province. Hypertension consultations in Capiz and Iloilo peaked in the second week of December. As a proportion of all consultations, however, Antique spiked in the last week of November while Iloilo spiked in the last week of January.

REGION VIII In Region VIII, there have been 10,481 consultations for hypertension reported through SPEED, mostly from Leyte province. Hypertension consultations in Leyte appeared to increase and plateau from the time of the typhoon until mid December and decrease by the end of December. This was however, a reflection of total consultations in that time period.
