Cardiology Flashcards
Primary (essential) HTN
elevated systolic/diastolic BP as defined w/out a defined etiology
secondary HTN
elevated BP with an identified cause
resistant HTN
BP uncontrolled despite adherence to an appropriate 3 drug regimen, where all drugs are >50% recommended dose
Refractory HTN
patient w/ resistant HTN, who cannot be controlled on >4 meds
Masked HTN
bp consistently elevated out of offive , but does not met criteria for HTN in office
MAP
Normal range 70-110 (<60 concern for insufficient perfusion through organs)
HTN Urgency
severe HTN (>120 DBP) in asymptomatic pt
HTN Emergency
Severe HTN (>120DBP) with acute end-organ damage
HTN complications Brain
Brain:
Stroke, hemorrhage, cerebral atrophy and dementia
HTN risk factors
Age obesity family history race high NA+ diet alcohol abuse physical inactivity diabetes dyslipidemia Hostility/rage depression
Secondary HTN (common cause)
#1 Chronic Kidney Disease Renovascular disease/ renal artery stenosis Mineralocorticoid excess Sleep apnea / breathing disorders Medications Steroids birth control (High Estrogen) NSAIDS SSRI Sudafed Cocaine/amphetamines
Secondary HTN (Uncommon causes)
Pheochromocytoma
endocrine disorders
Coarctation of aorta
Renovascular HTN (cause)
Older pt: atherosclerosis
Younger: Fibromuscular dysplasia
HTN complications Eyes
Retinopathy, vitrious hemorrhage, imparred vision and blindness
HTN complications Kidneys
CKD,
End stage renal disease
HTN complications Cardiac
Coronary heart disease, ischemic heart disease Lft ventricular hypertrophy heart failure Acute Aortic Dissection Arterial aneurism Hypertensive emergency
HTN Diagnosis
BP readings > 2 office visits, must be weeks or months apart
Home BP readings >130/80 mmHh
daytime <135/85 mmHg
Nighttime <120/70 mmHg
