Oxygen saturation level during heart attack?

Low. Blood circulation is not good during a heart attack which makes it hard for air exchange.
Varies. If the heart is still beating and the patients lungs haven't filled with edema, the saturation s can be normal near the heart... But if there is no forward flow from the heart (it is effectively not beating), the lungs rapidly fill with edema, the oxygen in the blood falls, and the patient dies.

I had a major heart attack and now have CHF. My oxygen was always in the 90's. Now my oxygen level has dropped to the 80's sometime. Is my CHF worse?

Could be. Could be that you are retaining fluid in your lungs and therefore your oxygen saturation is decreasing. You should be feeling more short of breath if this were the case. Nevertheless, given this finding, a visit to your cardiologist is in order to check your vitals, weight, symptoms, diet, and medications, and make any adjustments necessary. Good luck!! Read more...
CHF. if the drop in oxygenation is due to worsening of heart failure, you should have more orthopnea and paroxysmal nocturnal dyspnea and of course the echo will show worsening of ejection fraction. Otherwise, one needs to look for pulmonary causes including recurrent pulmonary embolism, COPD and interstitial lung fibrosis . Read more...

Well I've had massive heart-attack in 2012, had an icd put in and now they say that 75% of my heart isn't blood or oxygen am I at high risk for avr?

Meds/close f/u. An ischemic cardiomyopathy (cm) such as you have requires close followup with your cardiologist and regular assessment for arrhythmia and heart failure. The icd helps guard against sudden death as a result of dangerous ventricular arrhythmias (one of the major risks with cm). The other risk is of worsening heart failure. Your meds seem reasonable (consider Carvedilol instead of metoprolol ). Read more...

My sister went with oxygen for 7 minutes and a heart attack she a diabetic and had very low blood pressure kidney damage will she have brain damage?

High risk. Hi. I'm sorry to say, but I think her risk of brain damage is pretty high. So is her risk of another heart attack. Best of luck to her! Read more...
7 minutes is a while. Was she found down and it was 7 minutes before any CPR was started along with respiratory support or was CPR started right away but it took 7 minutes to get an airway on her? The target time limit for before brain damage occurs is taken to be 4 minutes. Having said that everybody is different and therefore, if your sister is in a coma right now we must let 24 hrs. elapse before saying much more. Read more...
Not sure. Adults who are deprived of oxygen due to cardiac arrest for over 5 minutes usually suffer brain damage. However since she did not have a cardiac arrest and,despite very low blood pressure, she may have had enough cerebral circulation to avoid significant brain damage. However because of diabetes and smoking history, she may have come vascular disease which increases her risk. Hope for the best. Read more...
Here are some ... I assumed you meant "... without oxygen for 7 minutes ...". The insult to all tissues and organs under the described clinical scenario is bound to happen, but just a matter at what degree, which will manifest over time. Now, how to keep up a free-flowing circulation to nourish all temporarily O2-/nutrition-deprived tissues / organs is the key personal & professional task - yet, the only best hope. Read more...

I've always been underweight, but my diet has included (a lot?) saturated fat (92% dv per day) the past year, should I worry about heart attack?

I will recommend. You to get a lipid panel and check triglycerides, total cholesterol, HDL and LDL cholesterol. Also, balance your diet more with more proteins, complex carbohydrates, vegetables and less unsaturated fats. Being skinny do not always translate into being healthy. I will avoid saturated fats at all. Read more...

Lungs are clear (ct scan) heart is okay (echocardiogram, ekg) then why oxygen saturation levels are low?

Possibilities... There are many possible disorders that could have these test results. You should have pulmonary function tests since a ct scan does not tell anything about the function of the pulmonary system; only that the lungs look ok. Musculoskeletal disorders can have test results as you describe. You likely need to see a lung specialist to do a work-up and find out why your pulse ox is low. Read more...
