4. Factors that leads to Vascular Diseases:
• Blood pressure
• Weight
• Exercise level
• Diabetes
• Cholesterol level
Most of these factors have easy or readily available ways to measure
and keep track such as weight balances, glucose meters, apps to track
of exercise.
5. Why Non-Invasive cholesterol measurement?
• Cholesterol is the hardest to keep track of and thus the least
monitored.
• Currently the only solution to keep track of cholesterol is to get
blood analysis done at the hospitals which is not only inconvenient
and expensive but require blood samples.
Thus it critical to have a non or less invasive cholesterol monitor to
check cholesterol as often as necessary.
11. Cholesterol score[2]:
Total cholesterol
Less than 200 mg/dL: desirable
200-239 mg/dL: borderline high risk
240 and over: high risk
HDL (high density lipoprotein)
Less than 40 mg/dL (men), less than 50
mg/dL (women): increased risk of heart
disease
Greater than 60mg/dL: some protection
against heart disease
LDL (low density lipoprotein)
Less than 100 mg/dL: optimal
100-129 mg/dL: near optimal/above
optimal
130-159 mg/dL: borderline high
160- 189 mg/dL: high
190 mg/dL and above: very high
Triglycerides
Less than n150 mg/dL: normal
150-199 mg/dL: borderline to high
200-499mg/dL: high
Above 500 mg/dL: very high
12. Relation between ECG and cholesterol:
• In patients after a myocardial infarction, there is an ST segment
elevation that correlates to higher blood LDL or total cholesterol[3].
• ST segment resolution 30 minutes after successful angioplasty of IRA
was observed in 116 patients (77%), who were classified as group A,
whereas 34 (23%) presented ECG signs of no-reflow (group B).
• Cholesterol increases the open probability of cardiac KACh currents[4].
