The mainstay of treatment following acute recovery from a TIA should be to diagnose and treat the underlying cause. Most patients who are diagnosed at a hospital's Accident & Emergency Department as having suffered from a TIA will be discharged home and advised to contact their primary physician to organize further investigations. An electrocardiogram (EKG) may show atrial fibrillation, a common cause of TIAs, or other arrhythmias that may cause embolisation to the brain. An echocardiogram is useful in detecting thrombus within the heart chambers. Such patients benefit from anticoagulation. If the TIA affects an area supplied by the carotid artery, an ultrasound scan may demonstrate carotid stenosis. For people with a greater than 70% stenosis within the carotid artery, removal of atherosclerotic plaque by surgery, specifically a carotid endarterectomy, may be recommended. Some patients may also be given modified release dipyridamole or clopidogrel. This is a life threatening emergency. You can not tell the difference between a CVA (stroke) and a TIA in the field. Ensure the patient's airway remains open. A person having a stroke may suddenly lose consciousness. Get the patient to sit down. Watch for any changes in the patient's speech or level of consciousness. If the patient loses consciousness, monitor respirations and pulse and be ready to perform CPR. Look for muscle droop on one side of the patient's face, or weakness on one side of the patient's body. Note if the pupil in one eye is larger than the other. If possible, record the patient's pulse and respiratory rate every five minutes and provide this information to the EMS or the treating physician. There is almost nothing that can be done in the field for a patient suffering a stroke or a TIA. If you have oxygen, administer it at low concentration, high concentration if the patient has difficulty breathing. DON'T GIVE ASPIRIN. If it is a stroke, it might be caused by a blood clot (embolism) or a ruptured blood vessel (hemorrhage.) Aspirin is a blood thinner. If given to a person who is bleeding, it will make it worse. Incidentally, there is not much an EMS crew can do for a patient who is suffering from a stroke. If the ambulance is delayed, the best thing you can do is put the patient in your car and go to the nearest hospital without any delay. Seconds count.

I don t know if my husband has had a TIA. Several hours ago he complained about not being able to walk properly. He said if he concentrated and walked forcibly he felt in control but if he just tried to walk normally it was awkward and out of control. He has now gone to bed and is sleeping soundly. The symptoms had subsided somewhat over the evening. Should I be waking him and taking him to the hospital?

32yo male:Did the dr fail to diagnose a transient ischemic attack ? Sending me to eye doctor .?? Please help.? quick background...I am totally a hypochondriac, I have a habit of waking up with my right arm asleep. The first times I got this I thought it was a stroke (lol) because I couldn t make a muscle. forward to 2 and a half weeks ago. I have been seeing this small aura like thing in my right eye. (prism like fish scale) It lasts for about 5 to 15 seconds and then goes away. Its only in my right eye, happens several times in hour with increasing frequency. Its occupies a very small part of my visual field and always the same position(does not move). Been suspecting this might lead to a stroke or something and then 3 nights ago I awoke not with my right arm numb but COMPLETELY paralyzed.totally unmoveable. Within a minute (TIAs can last mere seconds to minutes) it was gone (but I did not get the same sensation of arm waking up i normally get(needles) it just came back. Then began to paralyze again for 30 secs and went away. dr thinks im too young. ive had episodes of atrial fibrillation b4. consider all details not just hypochondria and also please consider that my arm paralyzed again after unparalyzing itself.

My father, age 78, is in excellent health and only takes medication for hypercholesterolemia (low 200 s). He recently started Erythromycin for head and chest congestion and sore throat. After taking this for a few days he had blood blisters erupt in his scalp and ears. His head felt a lot of pressure and he was worried he might be having a stroke. His neck and head were stiff with some numbness in his right arm. He DC d the antibiotic and went to his doctor, who placed him on Prednisone. Now he is a little groggy and isn t feeling well so he stopped the Prednisone. He sounds weak and we aren t sure why he was put on the Prednisone. My question is - why take Prednisone if the blisters are drying up? What is the benefit versus the risks?

Have mild chest pains after walkng for 20 minutes. They last about 15 minutes and when I slow down they go away. The rest of the day I just feel somewhat tired. Had echo,stress test on tread mill and angiogram CT scan. They said my heart is fine but I have some indictation of blocked arteries. One of them appears to be about 55-70% but they do not want to do an angiogram with stent. I had a liver transplant last Dec 2009 and it is fine. I maintain a good BP and pulse rate is a little low. After walking my BP is about 119/65 and HR is 62. Always, but I do have morning hypertension and am taking Cozaar and Norvasc along with Prograff,Imuran--Immunosurpressants for LIVER and Bactrim. The seem to cause headaches EVERY night about 2am that last for several hours. thought I was having a stroke but they ruled that out. Went to ER several times thinking that I was having a heart attack. EKG shows nothing and the heart enzyme tests are negative. I am puzzled. My dentist who is an avid runner said that I may be having ANGINA and to take my NITRO with me. I don t want to stop walking but this has been gpoing on for 3 months and nothing has been diagnosed? Thank You.
