Doctor insights on: Incidence Atrial Fibrillation Post Menopause Thyroid Hrt

Share

Incidence (Definition)

...That is a measure of the risk of developing some new condition within a certain period of time. The incidence rate is the # of new cases per population that develop a disease over a period of time. So, in a population of 100, if 5 people develop the disease within 5 years, the incidence rate is 5% over 5 years. Compare to 'prevalence', which measures the total # ...Read more

Names of most suitable ssri antidepressant needed for multiinfarct stroke dementia patient, 67, with minor congestive heart failure, atrial fibrillation, diabetes. Dosage and duration info appreciated.

Names of most suitable ssri antidepressant needed for multiinfarct stroke dementia patient, 67, with minor congestive heart failure, atrial fibrillation, diabetes. Dosage and duration info appreciated.

SSRIs: There is some evidence that ssris help with post stroke remodeling where the brain works on regrowing connections between brain areas that were not killed by the stroke. There is also evidence they help prevent post stroke depression that is very common. Not much reason to think one ssri is better than another. See your prescriber for specific dosage recommendations. ...Read more

Seizures can cause: an increase in heart rate however not the other way around. Defining the nature of the heart rate response is important. You need to see a health care provider and have them obtain the appropriate testing. ...Read more

If atrial fibrillation, after aortic valve replacement (in female 79), how is this usually corrected? Bisoprolol, metoprolol , sotalol already tried.

If atrial fibrillation, after aortic valve replacement (in female 79), how is this usually corrected? Bisoprolol, metoprolol , sotalol already tried.

Cardioversion?: Initially with rate control and anti-coagulation. If the atrial fibrillation is causing you symptoms, then a controlled and timed shock to the heart, called cardioversion, can be administrated tito regulate your heart. This is an outpatient procedure. Discuss with your doctor. ...Read more

30% heart functioning, severe LV dysfuntion, diabetic, hypertension, 54yrs old, highrisk CABG suggested, wht can be the success rate?

30% heart functioning, severe LV dysfuntion, diabetic, hypertension, 54yrs old, highrisk CABG suggested, wht can be the success rate?

Surgery: There is no clear cut answer. Only the cardiovascular surgeon that is involved in your care might give an estimate based on his/her experience. If you had a cath that suggested triple vessel disease, or anatomy not otherwise amenable to stenting, and CABG is offered, would suggest that you take it, since that can add many years of better quality life. ...Read more

PCOS, Endometriosis, Heavy Cycles, 33yo, tubal ligation 3 yrs ago. Would an endometrial ablation lessen my symptoms/cancer risks?

PCOS, Endometriosis, Heavy Cycles, 33yo, tubal ligation 3 yrs ago. Would an endometrial ablation lessen my symptoms/cancer risks?

Maybe not: Endometrial cancer can be obscured by endometrial ablations if it is not ruled out prior to the procedure by biopsy. Many women continue to have bleeding post endometrial ablation procedures, and the most likely conclusive treatment is hysterectomy if you no longer desire children. ...Read more

35 years, childless, hypothyroidism, 50 mcg Thyronorm daily. Read long term use of thyroid HRT can increase risk of breast cancer. Is this true?

35 years, childless, hypothyroidism, 50 mcg Thyronorm daily. Read long term use of thyroid HRT can increase risk of breast cancer. Is this true?

No: this medication is a synthetic Thyroid hormone which you need to survive. The levels should be monitored and adjusted by a doctor. It should not increase your Breast cancer risk. The replacement hormones people use for hot flushes (estrogen/progesterone) during and after menopause do cause increased risk. ...Read more

What can cause high TSH level after several years of Synthroid (thyroxine) for post ablative (graves) hypothroidism?

What can cause high TSH level after several years of Synthroid (thyroxine) for post ablative  (graves) hypothroidism?

Usually low Thyroid : Post ablative hypothyroidism is a condition where the thyroid gland is not functioning well and thus the patient needs more thyroid hormone. A "high tsh" actually mean there is not enough thyroid in the blood, thus an increase in dosage of the synthroid (thyroxine) is needed. Go see your family doctor and he/she will make adjustments and recheck the TSH level. This is very sensitive to thyroid in the body. ...Read more

Normal lab results, hyper thyroid symptoms. (tachycardia/insomnia) is Synthroid (thyroxine) or armour preferred? Possible adrenal issue?

Normal lab results, hyper thyroid symptoms. (tachycardia/insomnia) is Synthroid (thyroxine) or armour preferred?  Possible adrenal issue?

Not for hyper: Adding thyroid hormone replacement to a hyperthyroid gland will exacerbate the problem. If there is underlying adrenal insufficiency, adrenal crisis is more likely to occur in someone with hyperthyroidism. Highly recommend endocrine evaluation if you have these issues. ...Read more

Take bisoprolol intermittent resting heart rate of 165 + . age 49. causesplease?

Take bisoprolol  intermittent resting heart rate of 165 + . age 49. causesplease?

If you really have: a resting heart rate of 165 BPM then you need to be evaluated as soon as possible or you will be likely to develop a tachycardia mediated cardiomyopathy. Bisoprolol is not being sufficient for your management. Follow up with a Cardiologist or an Electrophysiologist as soon as you can for a more thorough evaluation and appropriate management plan. ...Read more

How many years must you have lone atrial paroxysmal fibrillation before heart failure is likely? Thanks!

May not: Atrial fibrillation, if the rate is controlled, may be present for many years without increasing the risk of heart failure. Anticoagulation is necessary in most cases to reduce stroke risk. ...Read more

Does hormone replacement therapy (hrt) increase a woman's risk for heart disease or not?

Does hormone replacement therapy (hrt) increase a woman's risk for heart disease or not?

Yes and no: It reduces the risk of developing plaque which reduces long term risk. However, it increases the risk of forming clots, especially in smokers, which is the final step leading to stroke or heart attack. ...Read more

Friend had thyroid cancer, total thyroidectomy. 15 yr hi-dose Synthroid (thyroxine) as suppression. Kidney eGFR now 47, sodium 131. Any connection likely? Age 70

Friend had thyroid cancer, total thyroidectomy. 15 yr hi-dose Synthroid (thyroxine) as suppression. Kidney eGFR now 47, sodium 131.  Any connection likely? Age 70

Not likely related: Hi. It is not likely the history of thyroid cancer and TSH suppression are related to the low eGFR or hyponatremia. eGFR falls with age, and hyponatremia is the most common electrolyte abnormality we see; both have multiple potential causes, but mild TSH suppression is not a likely one. Your friend can talk with his/her endocrinologist to see if there is any connection or needs further work up ...Read more
