Q: 

What are the signs of a heart attack?

A: The onset of symptoms in myocardial infarction (MI) is usually gradual, over several minutes, and rarely instantaneous.[48] Chest pain is the most common symptom of acute myocardial infarction and is often described as a sensation of tightness, pressure, or squeezing. Chest pain due to ischemia (a lack of blood and hence oxygen supply) of the heart muscle is termed angina pectoris. Pain radiates most often to the left arm, but may also radiate to the lower jaw, neck, right arm, back, and epigastrium, where it may mimic heartburn. Levine`s sign, in which the patient localizes the chest pain by clenching their fist over the sternum, has classically been thought to be...

Q: 

Is there any evidence that Angiotension Receptor Blockers should be used in patients who have had a previous MI which was complicated by LV dysfunction?

A: In the PRODIGY guideline on “Heart failure”, (1) it says the following: “Two angiotensin-II receptor antagonists (AIIRAs) are licensed for heart failure, with restrictions:  - Candesartan is licensed for the treatment of heart failure with impaired left ventricular systolic function.  - Valsartan is licensed for the treatment of left ventricular failure or systolic dysfunction following myocardial infarction.” In the section “Evidence for angiotension-II receptor antagonists in the treatment of heart failure” it goes on to say: “As part of the VALIANT trial, people with post-infarction heart failure were randomized to valsartan (n=4909) or captopril (n= 4909)...
Q: 

Overview of effects of ACE-Inhibitors on cardiovascular diseases

A: Angiotensin-converting-enzyme inhibitors, also known as ACE Inhibitor, are a class of medications that are used primarily for treatment of treatment of hypertension and congestive heart failure. Examples of ACE-Inhibitors include Captopril, Zofenopril, Enalapril, Ramipril, Perindopril, Lisinopril and Fosinopril. ACE inhibitors reduce arterial pressure by inhibiting angiotensin II production and increasing bradykinin and the vasodilating prostaglandins. ACE-Inhibitors have been shown to reduce the risk of death, stroke, diabetes, myocardial infarction, nephropathy and renal impairment. ACE Inhibitors are effective for a wide range of patients including those with history of myocardial

Q: 

Could you provide me with any research or guidelines on the risk/benefit of using Aspirin post MI in someone already using Warfarin?

A: A 2002 paper, published in the NEJM seems to be the major trial in this area [1].  This has been reviewed by Bandolier [2] and the Evidence-Based Medicine journal [3].  In a randomized, multicenter trial in 3630 patients, 1216 received warfarin (in a dose intended to achieve an international normalized ratio [INR] of 2.8 to 4.2), 1206 received aspirin (160 mg daily), and 1208 received aspirin (75 mg daily) combined with warfarin (in a dose intended to achieve an INR of 2.0 to 2.5). The mean duration of observation was four years.  The authors concluded: “Warfarin, in combination with aspirin or given alone, was superior to aspirin alone in reducing the incidence of composite events after an acute myocardial
Q: 

What is the significance of ventricular ectopic beats and supra ventricular ectopic beats in a 24 hour ecg. Is there any significance of bigeminy or trigeminy?

A: We searched the TRIP, Cochrane and Medline databases but found no robust evidence for further investigation of ventricular, supra ventricular Ectopic beats, bigeminy or trigeminy in asymptomatic patients.   We cannot make the clinical decision as to whether further investigation is warranted for an individual patient, but can report the evidence available on the significance of the condition. E-medicine has a chapter on Ventricular Premature Complexes (1) (synonymous with Ventricular ectopy) in which it states: Ventricular premature complexes (VPCs) are ectopic impulses originating from an area distal to the His Purkinje system. VPCs are the most common ventricular arrhythmia. Assessment and treatment of VPCs is challenging and complex. The significance of VPCs is interpreted in...
Q: 

What is the evidence that khat can cause heart problems?

A: We found a number of studies that examined the effect on khat on heart problems.  A 2005 Yemeni case-control study looked at the khat chewing as a risk factor for myocardial infarction [1].  They reported: “RESULTS: Khat chewing was significantly higher among the AMI case group than control group (OR = 5.0, 95% CI 1.9-13.1). A dose-response relationship was observed, the heavy khat chewers having a 39-fold increased risk of AMI. CONCLUSION: This study indicates that khat chewing is associated with AMI and is an independent dose-related risk factor for the development of myocardial infarction.” A 2000 study looked at the effects of khat on blood pressure in healthy...
Q: 

Steps to be taken for first heart attack immediate?

A: take bayer. really it does help I am narrating finger therapy for immediate prevention of heart attack: Fold ur first finger(index finger) and touch the bottom of ur thumb, now join the middle finger and ring finger i.e. 2nd and 3rd finger and touch the tip of ur thumb to the tip of joined fingers and keep the little finger straight. U can do it for both hands and whether u r lying down or sitting in a chair do it with both hands and if u r sitting then preferably put ur elbow to your sides and ur hands will extend to ur knees. This will 99% prevent the heart attack at least till the time the doctor is available. Alternatively just cut the tip of ur little finger and let it bleed. This is another remedy but not experimented by me or my associates. The first remedy has been experimented...


Q: 

How do people get cure from Heart Attack ?

A: The subject of a heart attack doesn''t not belong in a paper on infectious dieases unless the attack was caused by an infectious prcess such as endocarditis A heart attack happens when the heart muscle gets damaged by something. Could be several things. You can RECOVER from a heart attack, but there is NO cure. Once damaged it just takes time to repair itself as best it can. This will depend on how much damage was done and other organs affected. Check out these sites: www.prevention.com www.webmd.com Or type heart attack into ANY search engine and it will give you signs, symptoms, prevention, etc. A whole shite load of info out here. Nothing like waiting till the last minute to research something that has a million different sites and symptoms. More than 1 million Americans have heart...


Q: 

former cocaine use and potential heart damage

A: Hi, With the lifetime use of cocaine rising, adverse reactions to cocaine use have resulted in a situation wherein it has become necessary to consider cocaine related complications in the differential diagnosis of various disorders, particularly ischemic events in young adults. The cardiovascular complications include, - angina pectoris, - acute myocardial infarction, - arrhythmias, - accelerated atherosclerosis, and - cardiomyopathy. Cigarette smoking causes vasoconstriction of the coronary arteries through an ?-adrenergic mechanism similar to that of cocaine. Several recent studies have shown that the deleterious effects of cocaine on myocardial oxygen supply and demand are exacerbated...
