Coronary heart disease overview Flashcards
What is stable accumulation of flow restriction
Angina
What does a stable plaque leads to
Unstable plaque->Transient ischemia->Cardiac arrest
What doe saccule occlusion lead to
Acute MI->cardiac arrest
What does Chronic closure lead to
Scar formation->Cardiac arrest
What do you call remodelling of the scar formation of the heart
Ischemic cardiomyopathy
What is type 2 MI
Troponin release during another illness->no evidence of recent plaque rupture
Patients should have:
symptoms of MI
Abnormal ECG
What are the clinical syndromes of angina
Visceral pain from myocardial hypoxia
Patterns of provocation, relief, timing
Risk factors
What is Pulmonary embolism and what are the symptoms
blood clot gets stuck in an artery in the lung, blocking blood flow to part of the lung
Breathlessness, dull
What is dissection of the aorta and what are the symptoms
Tear in the inner layer of the aorta
Tearing, excruciating, severe then eases
Can angina occur without a CHD
Yes
can cure with or without CHD
What is the first line of testing for CHD
Exercise testing
What is the second line of testing for CHD
Perfusion imaging
What is perfusion imaging
Radioactive substance is used to travel through the heart and only absorbed by health heart muscle
What is CT angiography
Injection of contrast material into the blood stream then CT
What is an angiography
Sheath inserted into artery
Catheter advanced from wrist/groin
X-ray contrast agent injected to outline coronaries
Video fluoroscope recorded images in multiple vies
