Hypertensive Diseases Flashcards
What blood pressure values define hypertensive heart disease?
140+/90+
What is normal blood pressure?
90/60 to 120/80
What is the most prevalent cause of coronary artery and myocardial disease in the US?
Chronic hypertension
The term hypertensive heart disease is used when the heart is enlarged with no other pathology present (TRUE/FALSE)?
TRUE
What are the two types of hypertension?
Essential (Primary)
Secondary
What is essential (Primary) hypertension?
Hypertension with no other pathology present related to soft risks such as genetics, poor diet, lack of exercise, and obesity
Primary hypertension increases with age and soft risks (TRUE/FALSE)?
TRUE
48 year old male patient with a blood pressure of 142/95. He claims to work 9-5 and stop at McDonalds on the way home from work 3-4 days a week to watch TV for the remainder of the night. He spends his weekends driving to his mom’s house five hours away to take care of her. He is overweight. What type of hypertension is described?
Primary (Essential) hypertension
What is secondary hypertension?
Increased blood pressure with a specific cause or a consequence of another primary condition (pathology)
What renal diseases can cause secondary hypertension?
Polycystic kidney
Renin-secreting tumor
Renal artery stenosis
Chronic glomerulonephritis
What is polycystic kidney disease? Does it cause primary or secondary hypertension?
Kidney is replaced by cysts and causes secondary hypertension
How does a renin-secreting tumor of a kidney cause secondary hypertension?
The tumor will cause increased renin secretion which converts more angiotensinogen into angiotensin I and then II which causes more aldosterone to be released from the Zona glomerulosa leading to hypertension.
How does renal artery stenosis cause secondary hypertension?
Atherosclerosis of the kidney will cause the macula densa to sense low kidney blood pressure (which the kidney needs to release urine). The kidneys will activate the RAAS system to increase blood pressure systemically when it it already hypertensive.
What is chronic glomerulonephritis? Does it cause primary or secondary hypertension?
Scarring of the kidney and causes secondary hypertension
What adrenal diseases can cause secondary hypertension?
Cushing syndrome
Conn
Pheochromocytoma
What is Cushing syndrome?
Hypercortisolemia (increased cortisol) in the blood often as a result of increased ACTH causing an increase in aldosterone and a decrease in sex hormones
What are signs of Cushing syndrome?
Moon face, truncal obesity, pencil thin arms and legs, purple striae (stretch marks), buffalo hump
Patient presents with a blood pressure of 150/92, truncal obesity, and stretch marks. The patient’s cortisol levels are in normal ranges. What is a working diagnosis for this patient?
Conn syndrome
