2026-2027 Latest Update!!!
AAA- Abdominal aortic aneurysm - ANSWER-Severe tearing pain
radiating to back and abdomen
Acute Coronary Syndrome - ANSWER-Myocardial Infarction
Unstable Angina
Acute Coronary Syndrome - ANSWER-sudden obstruction of coronary
blood flow results in acute myocardial ischemia
ADH- Antidiuretic hormone - ANSWER-Released from the pituitary
because of
Decreased BP
Decreased blood volume
Increased osmolality
Causes enhanced reabsorption of water
,Adventitia - ANSWER-Supportive connective tissue
Afterload - ANSWER-The resistance the chambers have to push against
to eject blood
Anaphylactic Shock - ANSWER-Antigen/IGE antibody reaction
Vasoactive chemicals released
Histamines
Bradykinins
Bronchoconstriction
Peripheral vasodilation
Increased capillary permeability
Shock occurs when peripheral dilation is massive
Causes "pseudo" hypovolemic shock
Onset of symptoms 2-30 min of exposure to antigen
Anaphylactic Shock manifestations/treatments - ANSWER-Initially
Anxious
Increased HR and RR
Followed by...
Hypotension
Urticaria and pruritus
Impending doom
Angioedema
,Bronchoconstriction
Wheezing
Cyanosis
Stridor
Prevention or removal of cause
Airway, Epinephrine, Antihistamine
Aneurysm - ANSWER-Arterial wall deteriorates and bulges out
death occurs within minutes of rupture
surgical repair, smoking cessation and control BP
Angina Pectoris- chest pain - ANSWER-Crushing or squeezing
occurs intermittently
can be chronic or acute
Categories:
Stable Angina
Prinz metals Variant Angina
Unstable Angina
Aorta->Artery->Arterioles - ANSWER-Principal tissue is smooth muscle
Aortic Regurgitation - ANSWER-Blood leaks from aorta back to left
ventricle
↑ left ventricle pressure
Ventricular hypertrophy →ischemia and left side heart failure
, May lead to L-sided HF
C/O throbbing or pounding because of large LV stroke volume-
bounding pulse
Aortic Stenosis - ANSWER-Calcium deposits on the aortic cusps
Obstructs aortic flow
↑ left ventricle pressure
Ventricular hypertrophy →ischemia and left side heart failure
May lead to L-sided HF
Signs and Symptoms
Syncope
Low systolic BP
Faint pulses
Angina relieved by rest
Arterial blood pressure - ANSWER-produced by the force of left
ventricular contraction overcoming the resistance of the aorta to open
the aortic valve
Measured by:
A-line (direct)
Mercury sphygmomanometer (preferred method)
Dina map (Not as accurate)
Arterial thrombus - ANSWER-Symptoms of this clot:
