Ischemic heart disease |
No enough oxygen to the heart muscle |
|
|
|
Causes of ischemic heart disease |
1)Atherosclerosis (in coronary artery ———2)severe anemia 3)Carbon monoxide (high affinity to haemoglobin than oxygen 4) Vado-spastic 5)drugs(cocaine) |
|
|
|
How cocaine effects generally |
Cocaine inhibits neurotransmitter reuptike mechanism so neuroepinephrine will stimulate sympathetic nervous system and severe vasoconstriction and stroke and acute mi |
|
|
|
amphetamine |
Heptagon. Increases releases of neuroepinephrine causes euphoria. |
|
|
|
Atherosclerosis formation |
Endothelial injury LDL LDL oxidation will trigger immune cell and macrophages will come (foam cells ) and then smooth cell proliferation will begin and forms(((((()plague)))))) |
Risk factors of ischemic heart disease |
|
|
Risk factors of ischemic heart disease? |
Modifiable 1)Hypertension (Endothelial injury )(increasing demand by hypertrophying ventricles 2)hyperlipidimias(ldl) 3)diabetic (lypolysis) 4)smoking(oxygen stress oxidant) Non modifiable 1)age 2)male 3)family history My be female after menabosal

|
Stable angina |
Atherosclerosis Starts second decade of life Symptoms appear when 70%of artery is occluded Symptoms with exertion (bcz the heart rate and the contraction will increase and the myocytes need more blood (Chest pain increased by exertion and relieved by rest and nitrates) |

|
|
|
How nitrates work |
Cause vasodilation for venous and decreases after load decrease of stretch decrease contractility |
|

Non modifiable risk factors |
Gender male Family history Old |
|
|
|
Acute coronary syndrome |
Rapture of atheroma And platelets will aggregate And cause total or subtotal obstruction |
|
|
|
Acs |
ECG (nstemi) subendocardial infraction /or just ischemia
