Session 35: Identification of Patients with Hypertension Total Session Time: 120 minutes + 2 hours Assignment Prerequisites • None Learning Tasks By the end of this session students are expected to be able to: • Describe Causes of Hypertension • Describe Types of Hypertension • Describe Major Signs and Symptoms of Hypertension • Explain Treatment Of Hypertension • Explain Prevention and Control of Hypertension Resources Needed • Flip charts, marker pens, and masking tape • Black/white board, chalk and whiteboard markers • Computer and LCD Projector SESSION OVERVIEW |Step |Time |Activity/ |Content | | | |Method | | |1 |05 minutes |Presentation |Introduction, Learning Tasks | |2 |05 minutes |Presentation |Cause of Hypertension | |3 |20 minutes |Presentation |Types of Hypertension | | | |Buzzing | | |4 |15 minutes |Presentation |Major Signs and Symptoms of | | | | |Hypertension | |5 |20 minutes |Presentation |Treatment of Common Hypertension | |6 |40 minutes |Presentation |Prevention and Control of | | | |Small group |Hypertension | | | |discussion | | |7 |05 minutes |Presentation |Key Points | |8 |05 minutes |Presentation |Evaluation | |9 |05 minutes |Presentation |Assignment | SESSION CONTENTS STEP1: Presentation of Session Title and Learning Tasks (5 minutes) READ or ASK students to read the learning tasks and clarify ASK students if they have any questions before continuing STEP 2: Causes of Hypertension (5 minutes) • Hypertension or high blood pressure is a chronic medical condition in which the blood pressure in the arteries is persistently raised • Blood pressure is expressed by two measurements: o The systolic pressure occurs when the left ventricle contract o The diastolic pressure occurs when the left ventricle relaxes before the next contraction • Normal blood pressure at rest is within the range of 100–140 millimeters mercury (mmHg) systolic and 60–90 mmHg diastolic. • Hypertension is present if the blood pressure is persistently at or above 140/90 mmHg for most adults STEP 3: Types of Hypertension (20 minutes) |Activity: Buzzing (5 minutes) | | | |ASK students to pair up and buzz on the following question for 2 | |minutes | | | |What are the types of hypertension? | | | |ALLOW few pairs to respond and let other pairs to add on points not | |mentioned | | | |WRITE their response on the flip chart/board | | | |CLARIFY and SUMMARIZE by using the content below | Hypertension is classified as either: • Primary (essential) hypertension defined as high blood pressure with no obvious underlying cause. o About 90–95% of cases are categorized as primary hypertension • Secondary hypertension; defined as hypertension due to an identifiable cause o Accounts for remaining 5–10% of cases of hypertension, o Causes of secondary hypertension; ▪ chronic kidney disease, ▪ pregnancy ▪ alcohol ▪ narrowing of the aorta or kidney arteries ▪ Endocrine disorder e.g. excessive aldosterone, cortisol, or catecholamines ▪ Drugs such as corticosteroids, non-steroidal anti-inflammatory drugs [pic] STEP 4: Signs and Symptoms of Hypertension (15 minutes) • Hypertension usually does not cause symptoms initially • Some patients report; o Headaches (particularly at the back of the head and in the morning) o Vertigo, o Tinnitus (buzzing or hissing in the ears) o Altered vision or fainting episodes • Sustained hypertension over time is a major risk factor for: o Heart disease o Coronary artery disease o Stroke o Aortic aneurysm o Peripheral artery disease o Chronic kidney disease STEP 5: Treatment of Hypertension (20 minutes) • Refer patients to the hospital for investigations and initial treatment and follow up may be even done at dispensary or health centre • Antihypertensive medications are available for treating hypertension • First line medications for hypertension include: o Tthiazide – diuretics e.g. hydrochlorothiazide o Calcium channel blockers, e.g. diltiazem o Angiotensin converting enzyme inhibitors e.g. captopril o Angiotensin receptor blockers e.g. losartan ▪ These drugs may be used alone or in combination ▪ The majority of people require more than one medication to control their hypertension. STEP 6: Prevention and Control of Hypertension (40 minutes) |Activity: Group discussion (30 minutes) | | | |DIVIDE students into small manageable groups | | | |ASK students to discuss on the following question | | | |What are preventive and control measures of hypertension? | | | |ALLOW students to discuss for 15 minutes | | | |ALLOW few groups to present and the rest to add points not mentioned | | | |WRITE their response on the flip chart/board | | | |CLARIFY and SUMMARIZE by using the content below | • Lifestyle changes are recommended to lower blood pressure, before starting drug therapy. o Maintain normal body weight for adults (e.g. Body mass index 20 – 25 kg/m2) o Reduce dietary sodium intake o Engage in regular physical activity e.g. Walking o Limit alcohol consumption • consume a diet rich in fruit and vegetables • Stop smoking and reduce intake of dietary saturated fat and cholesterol • Lifestyle modification may lower blood pressure as much as antihypertensive drug • Patient education o Hypertension is a lifelong disorder ▪ Long-term commitment to lifestyle modifications and pharmacological therapy is required. ▪ Repeated in-depth patient education and counselling improve compliance and reduce cardiovascular risk factors. STEP 7: Key Points (5 minutes) • Hypertension is diagnosed by properly measuring elevated blood pressure at three or more separate occasions based on 2 or more readings. • Treatment approach in hypertension is based upon its severity by classification ranging from non pharmacological to pharmacological. • Patient’s education repeatedly carries a great role for optimal control of hypertension by lifelong commitment to lifestyle modification and drug therapy. STEP 8: Evaluation (5 minutes) • What is hypertension? • How is hypertension classified? •
