572651 tn?1530999357 I have nitroquik - sublingual nitroglycerin - to take if I have angina pains - this morning about 5 am I was miserable and couldn't tell if it was heart or ms symptoms and I took one. As always it stopped my discomfort, depressed my already low blood pressure and I went to sleep for about 3 hours. I've used nitroquik for the past 3 months or so and it always stops the pain and gives me relief within minutes.
1560697 tn?1295599961 E/A, it seems, in relation to preload, would not be dependant on pre-load, but preload would be dependant on the volume of blood going into the left ventricle during the E/A filling phases and the ratio does not change to the extent that more blood is pumped (A phase) into the LV than rec'd during "E" phase. Do you have an example where there could be a change in the A/E ratio? Hope this provides a perspective, and if you have any follow up questions you are welcome to respond.
Avatar f tn I would be concerned about CHF if I were at your house on a call! Especially with your respiratory ailments you describe. How have your blood pressures been? Multiple things can cause chf such as renal insufficiency, fluid overload, water retention from these disorders can sometimes be managed by weight control and exercising good dieting. Foods with high sodium levels can cause water retention. If I were you, I would see your PCP without delay.
Avatar f tn I asked my cardiologist for the results and diagnosis of 3 tests that were done. I had a Thallium Stress w/o exercise, also a Vascular 'doppler' (I think) and an Echocardiogram. The cardiologist just sent me her interpretation of the test, though she did not tell me what her 'interpretation' was of each test. I thought that this 'interpretation' in her words was something to be concerned about. "Left ventrical diastolic dysfunction with preload reduction.
Avatar n tn Hello, After 10 years of trying to get an answer, I finally got a diagnosis of cardiac preload failure, low VOxmax, and decreased AT. I have shortness of breath, palpitations/heart racing, chest pains, fatigue, lightheaded. Many many echos--three with bubbles. A PFO showed up on one. Normal cardiac cath--they couldn't see the PFO during the cath. Normal EKGs. Halters normal except for mild sinus tachycardia. Many pulmonary tests--all normal. I have MVP with trace regurgitation.
Avatar f tn If you miss a dose of Nitroglycerin Patch, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once. When used for long periods of time without a break, some people develop a physical need to continue taking Nitroglycerin Patch. This is known as physical DEPENDENCE. Do not suddenly stop taking Nitroglycerin Patch without your doctor's approval.
Avatar n tn I still had stable angina every time I did some for of cardio activity or is I ate something with sodium. I started using Nitroglycerin patches and even have the pills just in case my angina episode occurs. I had a date and I read online that you can't take viagra and any nitrates cause it can drop your blood pressure really low. So I stopped using my nitroglycerin for about 48 hours so I can take the Viagra.
1098952 tn?1270309713 If a person with HCM were to take nitroglycerin, the symptoms would worsen and the nitroglycerin could even cause a catastrophic deterioration in the person's condition".
Avatar n tn ed is correct nitro dilates vessels. I take a nitrate (isosorbide) for more than 6 years 3 times before going to gym for workout. My blood pressure does not drop between intervals...in fact I was told to have intervals of nitrate free period. It is true, nitro dilates the coronary vessels and prevents angina (chest pain). The patch should only be worn for up to 12 to 14 hours a day, or as directed by your doctor, but continued use with no interruptions can cause a tolerance for drug....
Avatar m tn I only take isosorbide prior to a workout, and nitro when engaged in an activity that brings on angina. I understand your doctors are suggesting taking isosorbide daily as aschemia does not always produce angina even though the heart cells are not getting sufficient blood supply. This can lead to a silent heart attack so the medication is recommended continuously whether there is angina or not and older people in general are likely to have a silent heart attack.
Avatar m tn The pain lasts anywhere from a few minutes to several hours. I have been prescribed nitroglycerin to take as needed for chest pain and this medicine surely helps. I've had several EKGs and cardiac enzymes done which were all normal. I also had a threadmill/stress test done which was normal. My cardiologist thinks the the probability of me having an occluded/blocked coronary artery is very low.
Avatar n tn The doctor said the left heart was okay but found a narrowing in the right heart which caused coronary spasms during the test. IV nitroglycerin during the test stopped the spasms and dilated the vessel. He did not mention any other problems and recommended sublingual nitroglycerin to treat the spasms as they occur.
Avatar n tn Cardiomyopathy has been ruled out. Everything has been ruled out. It is definitely preload failure. Preload failure is rare and almost always responds to fluid increase and/or an exercise regimen. I tried all of that a few times. It's amazing to see what doctors will do to get you out of their office when they don't know what to do with you.
Avatar f tn I've never heard of nitroglycerin being used to treat migraine, but glad that it worked. But if it keeps on, and sorry to tell you this, but you probably should see a doctor ASAP. It could be the sign of a coming stroke, since it is sudden and very painful. I started with a sudden very different migraine than any I had ever had before. It turned out that within 3 weeks, longer than usual as a gap in time, I had a full carotid artery dissection stroke.
Avatar m tn The same with his recent heart catherization was chest pressure. In the ER he was given 2 nitroglycerin, 5 minutes apart, the chest pressure went away after the 2nd nitroglycerin. Does any good specialist in cardiology think that my husband should have the open heart surgery for bypasses considering the risks regarding his age, his diabetes? I would appreciate very explanatory answers, easy to understand, what to do in my husband's situation. Thankyou.
Avatar n tn I assume the diagnosis of hyperreactive responses not only to the constrictor effects of acetylcholine, but also the dilator effects of nitroglycerin were detected diffusely in the epicardial coronary arteries of patients with coronary spastic angina. The goal of treatment is to control chest pain and to prevent heart attack. The pain is relieved by a medicine called nitroglycerin (dilates coronary vessels). You have been prescribed norvasc and that should relieve any chest pains.
Avatar n tn My 54 year old "healthy" husband received a stent yesterday due to a 99% LAD blockage! He is the typical type A personality and this only adds to his already stress overload. I realize we are lucky he is still here and thankful for medical technology. I am just concerned that this will forever be a constant worry for him. Any suggestions of how I can help him. Also I asked his MD about having nitroglycerin to have on hand and he said that this wasn't necessary???
Avatar m tn ) you prob had low preload and therefore bp. So your heart compensated. The only way to keep co up is via increased sv or hr. So basically co( cardiac out put)= stroke volume ( amount of blood for each pump) x heart rate. I think in your case totally benign.
Avatar n tn Monotrate, Vasotrate, Ismo, Imdur, Angicor), Isosorbide dinitrate (brand names: Sorbitrate, Isordil), Sublingual nitroglycerin tablets or spray (Angised, Angispan, GTN spray), Transdermal nitroglycerin patches or ointments (brand names: Top nitro, Nitroderm TTS, Myovin). Nitrates are also found in illicit drugs such as amyl nitrate (poppers). If you are not sure if any of your medicines contain nitrates, or if you do not understand what nitrates are ask you doctor or pharmacist.
Avatar m tn I'm a Raynaud's Phenomen patients who has the CREST syndrome and i use the nitroglycerin patches to control my raynaud's. Can you tell me if the patches used in this way would cause your acid reflux to be worse. When i took the lowest dose of nitroglycerin patches 0.1 didn't notice any but had to move up and now i do. Will this be something that my body may take an adjustment period for before i notice a different of not having symptoms again?
Avatar n tn You should talk to your doctor as you may be a good candidate for a low dose nitroglycerin patch which opens the coronary vessels to increase oxygen supply to the heart. How are you currently managing your COPD? What medications and inhalers are you using? are you on home O2?
Avatar m tn The doctors just did an ECG and say all is good. Is this possible? She is on constant Nitroglycerin and Morphine prn. Should she get a second opinion? What other procedures could she have done to take away this pain? She says the pain is getting more frequent and stronger. Thank you for your responses.
805943 tn?1238093647 Nitro can help some forms of esophageal spasm. Nitroglycerin is used with esophageal spasms (GERD). It is the one non heart related illness that nitroglycerin works in. However, that doesn't rule out a concomitant heart condition. Nitroglycerin is a vasodilator not only for your heart vessels but for the vascular system which then subsquently lowers your blood pressure. It even dilates the vessels in the brain which then usually gives the side effect of the headache also.
