I've been having chest pains randomly for about a week and I've been to the ER twice. Ekg and X-ray showed normal. Low potassium. Is heart attack likely?

I've been having chest pains randomly for about a week and I've been to the ER twice. Ekg and X-ray showed normal. Low potassium. Is heart attack likely?

Probably not: A heart attack without major risk factors at 19 is rare - low potassium is not necessarily normal - make sure that any of your medications couldn't be affecting your potassium - are you having any reflux symptoms? ...Read more

Myocardial Infarction (Definition)

Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & ...Read more

Should I worry about a heart attack if I am having symptoms of low potassium such as cramps?

Should I worry about a heart attack if I am having symptoms of low potassium such as cramps?

Probably not: At 34 yrs of age the odds of you having a heart attack is very small. Also cramps are not typical complaint during a heart attack. The symptoms are ususally, squeezzing chest pain, pressure, shortness of breath, nausea, sweatiness. The pain can move to neck, jaw, arms, or back. Leg cramps can be from low potassium but other causes too. ...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?

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?

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

How do you know whether you have a high or low risk to having a heart attack?

How do you know whether you have a high or low risk to having a heart attack?

Risk factors for MI: Certain factors contribute to the unwanted buildup of fatty deposits (atherosclerosis) that narrows arteries throughout your body, including arteries to your heart. You can improve or eliminate many of these risk factors to reduce your chances of having a first or subsequent heart attack.

Pcp has me taking 3 krill oil pills daily due to low omega 3's. I also take a low dose aspirin for heart attack prevention. Too much blood thinning?

Probably not: Omega 3`s and low dose Aspirin work at different levels. Omega 3`s replace cell products that release products of inflammation while the omega 3`s don't. Aspirin affects the blood platelets that normally control clotting and bleeding. ...Read more

Tests: Given your test results you do not appear likely to have calcified obstructive coronary artery disease at the present time. If you have plaque in your coronaries it doesn't appear to be highly obstructive at the present. We can't say there are no plaques. ...Read more

If you have had a heart attack and now you have low ejection fraction what can be done to improve?

If you have had a heart attack and now you have low ejection fraction what can be done to improve?

It depends: On whether there is scarring or ischemia - or as is most common, a little of both. Ischemic areas do not get enough blood flow, but anything that improves that can improve cardiac function.

This can be done with meds, and / or interventions.

Your doc can be a big help. ...Read more

I have high bad cholesterol and low good cholesterol. Am I at risk for widow maker heart attack daily? Could it happen at anytime due to this risk.?

Yes, but.....: It sounds like you have a family history of heart disease and are genetically programmed to make a unhealthy balance of cholesterols in your blood. This puts you at higher risk of a heart attack. If you google framingham. Org, you can enter your cholesterol and other simple information and get your 3-5 year heart attack risk.

How low would your blood pressure need to get to cause a heart attack or stroke?

How low would your blood pressure need to get to cause a heart attack or stroke?

It can happen: Blood pressure is an element and the very high can tear the aorta or the coronaries, but blockage by plaque and clot occurs with or without BP elevation.
The very low- shock can cause low coronary or brain blood flow.
Generally less than 70-80 mm hg is a concern.
Brain maintains good auto regulation from about 60 -160 if there is not other blockage or micro vessel disease. ...Read more

Hi, I had a heart attack on March 6, 2016. My cardiologue quickly jumped to the conclusion that I needed a pacemaker. I do not have low heartbeat.?

No: Most patients with heart attacks do not need pacemakers.
Pacemakers are only needed for patients whose heart rate is too slow or for whose electrical system does not conduct signals reliably from the top chambers to the bottom chambers of the heart. ...Read more

If my regular CRP (not hscrp) level is 0.10, HDL mildly low at 42, LDL and triglyc are low - does that mean I have a low risk for a heart attack? 26/f

If my regular CRP (not hscrp) level is 0.10, HDL mildly low at 42, LDL and triglyc are low - does that mean I have a low risk for a heart attack? 26/f

Yes: Females in your age group have an extremely low incidence of coronary artery disease. The chance of having heart attack is extremely low and would not likely be the result of typical coronary etiology of heart attack i.e. Plaque rupture. However heart attacks can occur from coronary dissection or other rare conditions. Pregnancy associated causes and blood clotting disorders are also rare. ...Read more

My BP sometimes goes very low. 96/50 today and I got dizzy, shaky hot & clammy. I sometimes get palps too. Only 32, mum had heart attack in 40s and PE?

My BP sometimes goes very low. 96/50 today and I got dizzy, shaky hot & clammy. I sometimes get palps too. Only 32, mum had heart attack in 40s and PE?

It is unlikely that: Your low blood pressure and associated symptoms are related to issues that would result in heart attack. The dizzy, clammy hot and shake are all a response to the low blood pressure and your body's attempt to correct it by releasing the hormone adrenaline. I suspect you have dysautonomia. (autonomic dysfunction) You should be evaluated for this diagnosis. ...Read more

I've heard that if you take low dose aspirin everyday it can help reduce clot formation that can lead to a heart attack. What exact part of clot forma?

Aspirin...: Aspirin causes the platelets to be "slippery" so they can't stick together. This helps prevent clot formation because the platelets are an integral part of clot formation. Hope this helps!!!! ...Read more

Can blood pressure indicate heart attack and bleed on the brain if so would it be high or low?

Can blood pressure indicate heart attack and bleed on the brain if so would it be high or low?

No, not reliably: Consequences of heart disease or stroke on blood pressure and visa versa, the effect of blood pressure on the heart or brain, is not uniform. Clearly markedly elevated blood pressure is a risk for stroke and increases the work on the heart, but patients with normal blood pressure can still experience a stroke or have a heart attack. There are many other factors to consider ...Read more
