Cardiovascular disease Flashcards
What are some Cardiovascular diseases
Acute bacterial endocarditis (ABE) Subacute bacterial endocarditis (SBE) Athrosclerosis Ischemic heart disease Coronary artery disease Myocardial infarction Congestive Heart failure Valvular disease Rheumatic fever Cardiac tamponade Tetralogy of fallot
Etiology of ABE
occurs during IV drugs without asepsis
Causative agent of ABE
Staphylococcus aureus
Affected site of ABE
Tricuspid valve
Disadvantage of having ABE
Reccurs
Differences between Asepsis, Disinfection and Sterilization
Asepsis - kill certain microorganism in living tissue
Disinfection- kill certain microorganism in non-living things
Sterilization- killing all microorganism
Layer of heart affected by ABE
Endocardium
Normal bacteria of skin
S. aureus
What must be done in patient with endocarditis that needs dental treatment?
ABE with fever on the day of tx: Prophylactic antibiotic 30mins to 1 hour before tx
ABE without fever: No prophylactic antibiotic
Prophylactic antibiotic for patient with endocarditis.
Amoxicillin 1-2g
Clindamycin- 600mg
Etiology of SBE
Occurs during dental procedure
Causative agent of SBE
Streptococcus veredans
Alpha-hemolytic streptococcus
Affected site of SBE
Mitral valve
The hallmark of endocarditis
FEVER
Cardiovascular disease caused by formation of plaques in vessels
Atherosclerosis (Atheroma)
Risk factors for atherosclerosis
Smoking
Hypertension
DM
Nephrosclerosis
Plaque in blood vessel means?
Accumulation of LDL or triglycerides
Less prone to heart disease
Acoholism
Action of alcohol in blood vessel
Vasodilation
Does menopause causes atherosclerosis?
No
It is the most common consequence of CORONARY ARTERY DISEASE
Ischemic Heart disease
Clinical sign of Ischemic heart disease
Angina pectoris
Angina pectoris is due to?
Vasoconstrcition
Type of angina seen in coronary artery disease and atherosclerosis but for healthy patient it is due to exertion or heavy exercise.
STABLE ANGINA
Type of angina due to severe coronary artery disease or oncoming MI.
UNSTABLE angina
Patient feels chest pain even at rest
Unstable angina
Type of angina due to vasosoasm that the patient feels intermittent chest pain
Variant (Pritzmetal)
Drugs used to treat Ischemic heart disease
Nitroglycerine (Glycerine trinitrate)
Ca channel blockers
Beta blockers
Amyl nitrate “poppers” through inhakation
Drug prescribed by dentist to treat angina
Nitrogycerine
onset of Nitroglycerine
Sublingual within 5 minutes
Action of Nitrogycerine
Vasodilation
Classic symptom of Coronary artery disease
Angina pectoris
Causes of Coronary artery disease
Atherosclerosis
Decreased oxygen in myocardium
Risk factors of Coronary artery disease
Hypertension Hyperlipidemia Smoking Obesity Being male
Most important drug in Coronary artery disease
Aspirin
Cardiovascular disease that is due to lack of blood flow in coronary artery
Myocardial infarct
Origin of MI
Deep femoral vein thrombosis
Type of infarct due to arterial occlusion
White MI
