How Does The Body Try To Compensate For Coronary Ischemia By Growing New Vessels
Good question: Through biochemical mechanisms stimulated by decreased blood flow to areas of the heart, small collateral arteries can form as branches of the larger coronary arteries in order to maintain as much blood supply to the heart as possible. These collateral arteries can often prevent permanent damage to the heart, but they rarely normalize the blood flow necessary for normal heart function. Read moreSee 1 more doctor answer
Coronary ischemia: The body will try to limit activity in order to decrease ischemia, so some people will feel fatigue or shortness of breath. Also often people have angina or chest pain with activity which limits activity. On the local level small vessels called collateral vessels can grow to bypass the blockage.

Microvascular ds: Coronary microvascular disease describes poor oxygen supply to the heart despite normal major arteries; the idea is that the tiny blood vessels don't allow normal flow. It is often discussed but is hard to diagnose. In my experience most people given this diagnosis don’t actually have it. Since you have had evaluation, it may be worth getting a 2nd opinion; consider a HealthTap inbox consult. Read moreSee 1 more doctor answer
45 yo f MRIs:. 2009:3 foci of white matter hyperintensity. Possible remote small vessel ischemia 2015:scattered areas of hyperintensity. Concerning?
Hard to know: Radiologists are trained to report on images without knowing anything about a patient. This way, everything gets included; even findings that are normal for most people. For a person with family history of early onset dementia and cardiovascular disease, for example, these findings could be meaningful. You can consider a virtual c/s w/ neurologist to review the images and in context. Read more
By blocking the flow: In young, healthy individuals the inner lining of the blood vessels is clean and smooth. Overtime, for many reasons, the inner surface of the heart blood vessels (coronary arteries) may start becoming bumpy/lumpy or blocked due to fat (cholesterol) deposits called "atherosclerotic plaque". This in turn reduces the amount of blood flow available causing "ischemia" (oxygen deprivation). Read more
Ischemia: Ischemia means inadequate blood flow. This can happen because the large size blood vessels are narrowed. It can also happen with normal large vessels and abnormal small blood vessels causing the inadequate flow. This is 'small vessel ischemia'. We don't have surgery or stents for 'small vessels' at this time. Read more
Not necessarily: Angina is a symptom of chest discomfort. Heart cells die only when the blood supply to the heart is stopped for at least 20 minutes. Angina may occur with no stoppage of blood to the heart, or it may occur in the presence of a damaging heart attack, known as myocardial infarction. Read moreSee 1 more doctor answer
Blood flow limited: It means that the heart muscle is not getting enough blood flow to meet its metabolic demands to carry out the required activities. This usually connotes a narrowing ("blockage") in one of the major coronary arteries that supplies heart muscle with blood, and hence oxygen. Read moreSee 1 more doctor answer

Overlap: Cardiac ischemia can be the result of coronary artery disease, cad, the latter being a progressive disease that can result in plaque/cholesterol building up in the coronary arteries and these stenoses or blockages can impair blood flow to the heart. Ischemia is the condition of blood flow and so oxygen being kept from a part of the body; cardiac ischemia is when this deprivation occurs in heart. Read moreSee 2 more doctor answers
MRI Few punctate T2 and FLAIR hyperintense foci in the periventricular white matter, likely related to chronic small vessel ischemia. What it means.
Would left coronary artery blockage produce ischemia of left ventricle and right axis deviation on ekg?
With congestive heart failure or coronary ischemia would the oxygen saturation shown on the monitor at hospitals drop?
Male 22. Nuclear stress show myo ischemia and angina. Coronary arteries clear and perfect? Have postural orthostatic tachycardia syndrome. Ideas?
Any way to reduce/eliminate cerebral small vessel ischemia/calcification reported on Er CT after running accident.
Ischemia: Acute ischemia is potentially reversible, but I suspect that what they found on your CT scan are chronic changes due to small vessel vascular disease. These changes represent damage already done and cannot be reversed. However, this is a relatively common age related finding, and depending on the severity may not result in any significant impairment. Read more
Ct scan showed Small vessel Ischemia. Cardioglogist quadruppled beta blocker after EKG. How does the ischemia effect my Kidney disease (stage 4)?
Vessels in both:
Without an actual exam, I can't give specific medical advice on your particular health.
Same things affect vessels EVERYWHERE. So, while strokes, or heart attacks don't hit the kidney. The same bad vessels are in all organs. Hi BP, diabetes, and cholesterol all clog vessels everywhere and affect all the organs (heart, brain, kidney). Treatable.
such bad heart disease, no blood gets to kidney. Read more
A person has single vessel coronary disease since 2000, now 2008 an still single vessel, 15months later severe triple, how unlikely is this?
I have minimal coronary heart disease in one vessel or two. What is my risk for a heart attack and how high is it?
Depends on more: Factors than just a diagnoses of "minimal CA. " to calculate your risk of a heart attack, you should see a cardiologist at least once every 2 years since your young. But if you exercise regularly (45 mins 5 days a week) watch your calories, normalize your weight for your height and eat a healthy diet you will decrease your chances SIGNIFICANTLY no matter what your risk is at this time.
