CV Risk Prediction Flashcards
general pathophysiology of MI due to hyperglycermia
- predisposition to hyperglycemia (DM I or II, genetic)
- oxidative stress rsults in endothelial injury via several mechanisms
- injured endothelium becomes inflamed, permeable and prone to thrombosis and abnormal angiogenesis
- Extravasation of oxidized lipid and activated monocytes lead
smooth muscle cells and expansion of medial layer
to foam cell formation and accumulation between endothelial and medial layer of the vessel
• Presence of this inflammatory material leads to migration of
in diabetes, which coronary vessels are more affected?
distal and multiple vessels are affected.
Why is heart disease different in diabetes?
- Early onset CVD in diabetes; people with diabetes experience CVD events on average 15 years before age and sex matched peers
acute vs chronic dysglycemia
chronic dysglycemia; level of glycemic control (or lack thereof) outside of vascular event
acute dysglycemia; hyperglycemia that occurs at the time of a vascular event (MI, Stroke)
Glycemic control and CV risk
- Tight glycemic control in type 1 diabetes is
associated with a 40-60% ___ in all
cardiovascular events
– Myocardial infarction – Stroke – Cardiovascular related death
Whether tight control in type 2 diabetes offers
the same macrovascular protection is ___
40-60% reduction in cardiovascular events
Whether tight control in type 2 diabetes offers
the same macrovascular protection is unclear
Glycemic Targets
• Type 1 and newly diagnosed Type 2- the target
should be__%
• Type 1 and newly diagnosed Type 2- the target
should be 7%
• Longstanding Type 2- 7% remains the ideal,
but duration of disease and other co-
morbidities may soften the target
diabetes therapies that are CVD protective
diabetes therapies that are CVD neutral
protective: SGLT2 inhibitors, GLP-1s, Metformin, and healthy behaviour interventions
neutral: sulfonylureas, DDP-4s, Insulin, Pioglitazone (?)
true BP lowering therapies for those with hypertension are better in improving CVD compared to glucose lowering strategies
true initially, but at the 10 year mark, its better to be lowering glucose
treatment threshold, and treatment TARGET in terms of blood pressure levels in high risk, diabetes, moderate risk, and low risk groups
Hypertension Rx in Diabetes
• Should target a blood pressure of
First line agest include:
<130/80
first lin agents include:
- ace inhibitors
- ARBs
- thiazide diuretics
- calcium channel blockers
___ is the main atherogenic particle
• LDL-c ___ is the cornerstone of
dyslipidemia therapies to prevent CVD
• Low __ & high __ seem to contribute to CV
risk, but interventions that target these
particles are not consistently helpful
LDL-c is the main atherogenic particle
• LDL-c lowering is the cornerstone of
dyslipidemia therapies to prevent CVD
• Low HDL & high TGs seem to contribute to CV
risk, but interventions that target these
particles are not consistently helpful
first line LDL lowering therpay
statins are first line (HMGCoa inhibitors)
