Why people experience chest pain when they have left ventricular failure resulting from myocardial infraction

---

Florita Santos, a middle-aged woman, is admitted to the coronary care unit with a diagnosis of left ventricular failure resulting from a myocardial infarction. Her history indicated that she was aroused in the middle of the night by severe chest pain. Her skin is pale and cold, and moist sounds are heard over the lower regions of both lungs. Explain how failure of the left ventricle might cause all three of these signs and symptoms (the ones in italics).

Please help
the biggest muscle in the heart is the left ventrical. it is responcible for pumping oxygenated blood throughout the whole body. the blood enters the left atruim from the lungs via the pulmonary vein, the only vein in the whole body that carries oxygenated blood. with this being said, with left ventricular failure, blood will back up in the lungs causeing "CHF" or conjested heart failure. CHF in a patient is almost diagnostic of left ventricle failure or weakness. this will cause the moist breath sounds, frothy red sputum, or awakening in the middle of the night and the need for 2 or more pillows to sleep.

as for the chest pain, chest pain can be caused by many things, being cardiac related, you must remember that the heart is a muscle with its own blood and oxygen supply. a micardial infarction is caused my lack of blood reaching a part of the heart starving it of oxygen cause the muscle to being to do die. now the pain most commonly discribed by heart attact (M.I) patients is left shoulder, jaw, arm or midsternal pain. and the common reason for this is simple when you thing of physiology. the vegus nerve, one of the largest nerves in the body, begins in the cerivcal spine, wraps around your left should, across the heart and down the body. furthermore; when the infarct, or dying tissue reaches a part of the heart where vegus receptor is it starves the nerve sending pain up towards the shoulder and is felt in one of the varies if not all of the places i described.

so with all this, you have a weakened left side of the heart, blood can not be pumped throughout the body as it did pre-m.i, so the body reacts with pale or cyanotic limbs and becomes sweaty due to the poor circulation and sympathic responce.'

What does preserved left ventricular systolic function mean?

---

My echo says that I have a normal LV and preserved LV systolic function. I went in for tachycardia (SVT)
So does preserved mean the same thing as "normal"?
Preserved means the same thing as normal.  (+ info)

Left ventricular hypertrophy with qrs widening and st elevation present in anterior leads. What does this mean?

---

, I hade an ekg done on 11/09/09 and this was the result. I have since had to have a stress test but have not received the results. Can anyone shed some light on this for me ? Thank You !
Your cardiologist ordered the stress test because the electrical measurements on the electrocardiogram can often mislead physicians in diagnosing the heart condition of left ventricular hypertrophy. Such a qrs waveform widening is a sign of left ventricular hypertrophy, but other screening tests should be done before a definitive conclusion can be made. So, unfortunately you will have to wait for the stress test results and your cardiologist's interpretation of the tests. Best of luck to you.  (+ info)

How long can the body live without the heart? I have Reoccuring Periocarditis/Left Ventricular Cardiomyopathy?

---

I have reoccuring periocarditis & LVC with some wall thickening. Let's say I just suddenly drop playing basketball or football or while I'm out for a 5 mile run or while I'm in the bedroom with my woman. Realistically what are the chances of my survival if my heart fails even with the administration of CPR. Also can a heart that has failed due to my condition be defibbed to restart?
I'm not sure, But I will pray for you.  (+ info)

What does it mean that I was shown to have a left ventricular ejection fraction of 55%?

---

I was also noted to achieve an exercise capacity of 12.8 METS. What does that mean? I am 55 years old if that is relevant.
its the fraction of blood pumped out of a ventricle with each heart beat.
Guess the 12.8 means your in good health  (+ info)

Chronic aortic stenosis can sometimes lead to left ventricular hypertrophy. Why?

---

Chronic aortic stenosis can sometimes lead to left ventricular hypertrophy. Why?
Due to chronic aortic stenosis,i.e.narrowing of the aortic valve,the oxygen-rich blood from the lungs which has finally reached left ventricle,the last chamber of the heart before getting distributed to various body parts through aorta,gets accumulated here since the outlet has narrowed down,thereby giving rise to ballooning and a thicker muscle mass in left ventricle which is the largest pumping chamber of the heart.Hence the left ventricular hypertrophy.  (+ info)

My partner has severe left ventricle dysfunction due to wegners granulamatosis what is life expectancy?

---

The consultant said his heart will deteriate. At the minute he's asystematic. The consultant said as the heart gets worse, there will be a chance for a transplant, as my husband is only 46 yrs. His heart at present is working at 30%. My husband still works full time but does get tired after a days work.
i wouldnt trust any answers you get to a medical query on here chick. Why dont you contact the British Heart Foundation and ask them to assist in your queries.  (+ info)

Is left ventricular hypertrophy a sign of HTN?

---

In my opinion it is. A sign is something you can sense, and if the ECG shows you something then you can label it a sign, right?
Left Ventricular Hypertrophy results from the heart having to pump against an increased peripheral vascular resistance. So technically yes. However, and more correctly it is a sign of ANY disease that increases the afterload. Not just hypertension.  (+ info)

what do you mean by DIFFUSE DISEASE OF LAD NORMAL LEFT VENTRICULAR FUNCTION OF THE HEART?

---

Angiogram does not suggest that the LAD is suitable for intervention of any kind , requires aggressive managment of his risk factors.
it means that the Left Anterior Descending artery has severe disease or clogged, they cannot stent it or to an angioplasty to the vessel b/c of the extent of the disease. the normal Left Vent function means that the strength of the heart muscle is good and there has not been an area of infarct (heart attack) Sounds like you have high risk factors for example smoking, obesity, high cholesterol, diabetes or other significant health issues. they will probably treat you medically with blood thinners and beta blockers.  (+ info)

What are the indicators to identify a Left Ventricular Ejection Fraction (LVEF) problem in a medical data?

---

I am analyzing a set of medical data to identify LVEF and heart failure problems. I am not sure which indicators and values to analyze. Thanks for helping.
The following is from wikipedia, but put simply it is the amount of blood ejected by the left ventricle.


By definition, the volume of blood within a ventricle immediately before a contraction is known as the end-diastolic volume. Similarly, the volume of blood left in a ventricle at the end of contraction is end-systolic volume. The difference between end-diastolic and end-systolic volumes is the stroke volume, the volume of blood ejected with each beat. Ejection fraction (Ef) is the fraction of the end-diastolic volume that is ejected with each beat; that is, it is stroke volume (SV) divided by end-diastolic volume (EDV):

In a healthy 70-kg (154-lb) man, the SV is approximately 70 ml and the left ventricular EDV is 120 ml, giving an ejection fraction of 70/120, or 58%. Right ventricular volumes being roughly equal to those of the left ventricle, the ejection fraction of the right ventricle is normally equal to that of the left ventricle within narrow limits.  (+ info)
