Coronary heart disease and cardiovascular disease

Coronary heart disease and cardiovascular disease?
I am just a little confused about the difference between coronary heart disease. To me it sounds like a disease that could be labeled under a cardiovascular disease. So...any ideas? so then since it has to do with the heart it would still be considered a cardiovascular disease?

Not really. It was a case of ignorance. In the past they had no idea about cholesterol and what it could do to the cardiovascular system. So if there was anything dark and deceptive about it, that was just pure ignorance. Greedy? Manipulative? Probably. Due to the aforementioned ignorance at lot of bogus treatments were made available by greedy entrepreneurs to treat heart disease. When, in truth, they just did not know what the hell was going on. The cholesterol-heart disease connection is not just a theory if that is what you mean. It is a fact. Ask any doctor that has had remove an artery blocked by cholesterol buildup.
2 :
Yes....type into google cholesterol myth lol and find your answer. Also, homocysteine...huge factor!...the leading factor in heart disease, stroke and many other conditions/diseases. The deceptive, greedy and manipulative part lol is to sell cholesterol lowering drugs...none of which show any difference in test studies at decreasing heart disease. 50% of people who have a heart attack have normal cholesterol levels. Also, the saturated fat is bad for you line meh~! Heart attack was 1 in 100,000 a century ago...and all they ate was saturated fat (natural fat). If there is cholesterol found in the arterial walls...it is there because homocysteine (an amino acid in the blood that is toxic to the body in high levels) is like glass running throught all your veins and arteries, allowing cholesterol and infections inside the arterial wall.... homocysteine also hardens the arteries with scar tissue. Today's poor diet and lifestyle all contribute to high homocysteine levels. At the end of the day it is money $$$$. When lipator (cholesterol lowering drug) is the best selling drug in the world, wouldn't you think heart disease would decrease...it hasn't...but profits have soared....case closed.

Oprah's doctor on her own show once claimed that 1 in 2 women in the US suffer or are potential victims of heart disease, with the possible consequences of becoming fatal if left untreated. It's the malignant, latent nature of heart disease that's most people don't understand. FACT #1: 150 years ago heart disease was virtually unheard of. Today it is the #1 cause of death in America. It kills nearly 30% of us. In fact, it kills more women than all forms of cancer, chronic lung disease, pneumonia, AIDS, diabetes and accidents combined. FACT #2: In one year, 407,000 patients had bypass surgery. Around 4% (over 16,000) of these patients died on the table or a few weeks later. That same year, the 400,000 patients who had angioplasty surgery didnâ€™t do much better â€” another 2 to 4% of these patients also died.

Did you know eating animal protein is directly related to heart disease

Did you know eating animal protein is directly related to heart disease?
Did you know eating animal protein is related to heart disease? I didn't know either, but after reading this book "The China Study" , there is no question in my mind... Don't take my word for it, this guy is a heavyweight researcher that was funded by lot's of gov. and cancer association grants... Animal protein is anything like dairy, meat, eggs, fish, etc. The only protein that safe and does not relate to heart disease is from plants ( soy, beans, etc ) I think that if I was preaching, this would look like this "don't eat meat" but I am just informing all of you of what I found out. I am going to be taking the advice in the book and eating less meat if any. If you are informed and choose to eat meat then it's your choice, but do it knowing the possible implications... Sure in life there is a 100% probability you will die. If you smoke, you know the odds, and I learned that in 2nd grade. Now if someone taught me about improper nutrition upping the odds for a lower quality of my health and possible premature death, I would appreciate that.

It is extremely common knowledge! Why do you think for years doctors have warned against eating too much red meat. However, I will eat what I want, thank you very much and you would be wise not to preach to other people. This is why you veggies get such a bad rap, you think you're better than everyone else and that no one else is smart enough to make up their own minds. Bugger off! ADDITIONAL Who the hell are you kidding? You were never informed about nutrition? What? Do you live under a freaking rock? And you are preaching when you assume you will teach all us "dummies" something YOU think we don't know. And you are a hypocrite to say "if you uniformed people continue to eat meat......etc" When by your own admission you are going to continue to eat meat, just cut back. Crimmines!

Yes, i've known for years. Unfortunately, since humans are omnivores, they need specific proteins from animal flesh. The key is MODERATION. Only a few ounces a day. There are people who are ABLE to be vegetarians only, but not everyone is capable of it, or wants to be a veg.

It's not just heart disease either.

Did you also know that riding in a car can lead to death, if some nut crashes into you? Did you know that eating vegetables can lead to death if you choke on an asparagus tip and no one's around to save you? Did you know that you can get lung cancer, even if you've NEVER EVER smoked in your life? All kinds of things in this world can kill us. And not eating animal protein is no guarantee of a long life... and even if it did give me a longer life, it would probably only extend my life by about a week or so. Anyway, I'll get heart disease through genetics. Diabetes, too, probably. The key is to make the most of every day you are alive. And remember that life is short. So eat dessert first.

This is very interesting. Why don't all meat eaters develop heart disease though? I'd rather live to be 85 and die of a heart attack than to develop a nasty protein deficiency in my mid-20s and be sickly for the rest of my life until I started eating meat again. The problem with studies like this is that someone makes some miraculous discovery that this and that cause cancer, and if you do so-and-so, you'll develop osteoperosis, etc. Haven't you ever sat back and noticed though that some years down the road, someone else does a study on the same subject and says, "Hey, guess what we just found out? 20 years ago when we scared the sh!t out of the whole world by announcing that doign this causes that--oops!

Kierra, I am not aware of any condition that demands four separate injections directly into the heart each day. It is a very difficult area to inject with any accuracy and the resultant scarring would be detrimental to the health of the heart. It is possible that the required medication may be administered through a cannula in a peripheral vein. There are many drugs that are intended to assist cardiac function that may be administered in this way. During a cardiac arrest manufacturers suggest that adrenaline may be injected directly into the heart through the chest wall if no other route is available (eMC, 2006). This can be a difficult procedure and should only be attempted by a competent clinician and when all other attempts to gain access have failed. There is a technique, useful in complex coronary interventions, wherein timed bilateral contrast injections are given in both coronary arteries. This technique is useful in chronic total occlusions in which the distal coronary vessel is not visualized except by collateral filling via the contralateral artery. ALL ANSWERS SHOULD BE THOROUGHLY RESEARCHED, IN ANY FORUM AND ESPECIALLY IN THIS ONE. - MANY ANSWERS ARE FLAWED. It is extremely important to obtain an accurate diagnosis before trying to find a cure. Many diseases and conditions share common symptoms.

What is a coronary heart disease? What are its symptoms, test, and treatment?
How is it detected during test?
Heart Diseases - 3 Answers
Random Answers, Critics, Comments, Opinions :
1 :
Coronary heart disease (CHD), also called coronary artery disease (CAD) and atherosclerotic heart disease, is the end result of the accumulation of atheromatous plaques within the walls of the arteries that supply the myocardium (the muscle of the heart). While the symptoms and signs of coronary heart disease are noted in the advanced state of disease, most individuals with coronary heart disease show no evidence of disease for decades as the disease progresses before the first onset of symptoms, often a "sudden" heart attack, finally arise. After decades of progression, some of these atheromatous plaques may rupture and (along with the activation of the blood clotting system) start limiting blood flow to the heart muscle. The disease is the most common cause of sudden death. Symptoms --- The symptoms associated with coronary heart disease may be pronounced, but the disease can also exist with noticeable symptoms. Chest pain (angina) is the most common symptom, and it results from the heart not getting enough blood or oxygen. The intensity of the pain varies from person-to-person. Chest pain may be typical or atypical. Typical chest pain is felt under the sternum (breast bone) and is characterized by a heavy or squeezing feeling, it is brought on by exertion or emotion, and it is relieved by rest or nitroglycerin. Atypical chest pain can be located in the left chest, abdomen, back, or arm and is fleeting or sharp. Atypical chest pain is unrelated to exercise and is not relieved by rest or nitroglycerin. Atypical chest pain is more common in women. Typical chest pain and age indicate the chance of a person having CHD. For example, a 65-year-old woman with typical angina has a 91% chance of having CHD, while a 55-year-old woman with atypical angina has a 32% chance of having CHD. Other symptoms include: Shortness of breath -- This is usually a symptom of congestive heart failure. The heart at this point is weak because of the long-term lack of blood and oxygen, or sometimes from a recent or past heart attack. If the heart is not pumping enough blood to circulate in the body, shortness of breath may be accompanied by swollen feet and ankles. Heart attack -- In some cases, the first sign of CHD is a heart attack. This occurs when atherosclerotic plaque or a blood clot blocks the blood flow of the coronary artery to the heart. The coronary artery was likely already narrowed from CHD. The pain associated with a heart attack is usually severe, lasts longer than the chest pain described above, and is not relieved by resting or nitroglycerin. Signs and tests------- There are many tests that help diagnose CHD. Usually, more than one test will be done before a definitive diagnosis is made. Some of the tests include: Electrocardiogram (ECG) Exercise stress test Echocardiogram Nuclear scan Coronary angiography/arteriography Electron-beam computed tomography (EBCT) -- the purpose of this test is to identify calcium within the plaque found in the arteries. The more calcium seen, the higher the likelihood for CHD. Coronary CT Angiography Treatment Return to top The treatment for CHD varies depending on the symptoms and how much the disease has progressed. The general treatments include lifestyle changes, medications, and sometimes surgery. Lifestyle changes may include: Losing weight A low saturated fat, low cholesterol diet to help reduce cholesterol Reducing sodium (salt) to keep high blood pressure under control Regular exercise Quitting smoking Medications may include: Cholesterol-lowering medication Antiplatelet agents, such as aspirin, ticlopidine, or clopidogrel, to reduce the risk of blood clots Glycoprotein IIb-IIIa inhibitors, such as abciximab, eptifibatide, or tirofiban, to reduce the risk of blood clots Antithrombin drugs, such as blood-thinners (low-molecular heparin, unfractionated heparin), to reduce the risk of blood clots Beta-blockers to decrease heart rate and reduce oxygen use by the heart Nitrates such as nitroglycerin to dilate the coronary arteries and improve blood supply to the heart Calcium-channel blockers to relax the coronary arteries and all arteries in the body, thus reducing the workload for the heart ACE inhibitors, diuretics, or other medications to lower blood pressure Percutaneous Coronary Interventions (PCI's) include: Coronary angioplasty (Balloon PTCA) Coronary atherectomy Ablative laser-assisted angioplasty Catheter-based thrombolysis and mechanical thrombectomy Coronary stenting (placing a tube in the artery to keep it open) Coronary radiation implant or coronary brachytherapy Dr.Brijesh cw1067bk@yahoo.com
2 :
Heart disease, or coronary artery disease, is the result of plaque (fat) building up in the arteries (vessels that take blood away from the heart and feed the body) that stem directly from the heart. As it gets worse and time goes on, the symptoms can include being short of breath with minimal exercise. The worst case scenario is when the plaque ruptures (breaks free from the lining of the artery) and clogs blood flow, resulting in a heart attack (death of cardiac tissue). The symptoms of a heart attack are usually chest pain in the center of the chest, radiating down the left side or left arm. The tests they use in the hospital are EKG's, (electrocardiogram) and blood tests including CKMB's (creatine kinase myocardial bands) and troponins. If the heart has been damaged permanently it will cause cell breakdown and release these substances into the bloodstream, which is what the tests look for. Next step is a stress test, where they measure the effect of exercise on the heart. If it is positive, they will then do a cardiac cath. They put a small tube inside the biggest artery of your leg, feed the tube up into your heart, inject dye and watch on an Xray to see the pattern of blood distribution. They can detect artery constrictions this way and use the catheter to insert stents if necessary to keep the arteries open. If it is really bad, they will send the patient immediately for open heart surgery. I hope this answer helps. :)

I would really recommend the www.imshredded.com program for you In order to gain muscle you have to lift heavy not long. If you can go on for around 3 hours then the weights that you are lifting are too light. Try finding a weight that you can only lift maximum 20 times. And keep going until it becomes easy then increase the weight. Try to keep your workouts between 40 -60 minutes Also, if you want to gain muscle/weight don't forget to eat a lot of lean protein like chicken and fish and get lots of rest. Your body needs time to rebuild the muscle. Try training every second day

Living standards, social class, food intake where they are buying their food and if they can afford to eat like white people can.

By far the majority of slaves imported to the Americas came from West Africa. While it appears that African Americans have a higher rate of hypertension than do West Africans in general, some biological evidence exists to suggest genetics is at play. Diet plays some role & it is uncertain if West Africans would display the same amount of hypertension as Americans, given the same diet. The methods of testing this would be to test West Africans living on a typical African diet & those living on a Western Diet. Some suspect that only those living on a high salt diet & having a general propensity toward hypertension survived the Atlantic crossing. One would be required to have several control groups: 1) West Africans on an African diet. 2) West Africans on a Western diet. 3) African Americans on an African diet. 4) African Americans on a Western diet.

A large portion of the standard American diet (SAD) includes excess animal protein in the form of meat, eggs, and dairy. Over 75% of African Americans and Hispanics have some form of allergy or intolerance to dairy, however, milk and dairy continue to be recommended through industry influenced media and government agencies. Diet is the #1 contributing factor when it comes to heart disease, hypertension, and stroke, along with other diseases of affluence such as diabetes, cancers, and osteoporosis. The SAD with excess animal proteins and unhealthy processed ingredients, additives, colorings, preservatives, sugar, fat, and salt have been shown to be correlated with high blood pressure and coronary disease. This is documented through research led by Dr. T. Colin Campbell, Dr. Neal Barnard, and many others. The scientific research showing this relationship start in the late 1800's. These diseases of affluence are primarily lifestyle related and have a weaker but statistically significant genetic basis. To determine whether the difference in populations is biological (genetic), you would need to control other variables that have an influence on the rates of heart disease, stroke, and hypertension. These include: + Sleep. + Exercise. + Smoking. + SAD versus vegetarian (animal protein consumption). + Alcohol consumption. + Drug (legal and illegal) consumption. There is clearly a genetic predisposition toward these diseases, however, the lifestyle factors above represent a greater threat to a person's health than genetic predisposition (contrary to the consensus reality promoted by industry influenced institutions). You need to define your population. A good model for this is "The China Study" by T. Colin Campbell, professor emeritus from Cornell. His study was of a heterogeneous populations from rural China. If you are able to establish a random sample of people, say in the more homogeneous US in your local region, you might be able to take a random sample of say 100 blacks and 100 whites. Before you start, you must state your hypothesis such as: Null Hypothesis: There is no difference in 'diseases of affluence' between blacks and whites when lifestyles are similar. Research Hypothesis: Blacks experience more 'diseases of affluence' then whites when lifestyles are similar. You would need to segment the population in such a way that comparison between each group has similar lifestyles. A vegetarian black population should be compared to a vegetarian white population with similar lifestyle. A SAD black population should be compared to a white SAD population with similar lifestyles. Your definition of terms and means to classify subjects should be determined ahead of time. Also, your conclusions are probably valid for the local population only. You might find that the differences are due to lifestyle differences, such as a greater percentage of whites who are 100% vegetarian. Your research should account for this possibility. Note that you might find that genetics account for a small, but statistically significant difference, like 3%, where as a lifestyle difference accounts for more like 60% of the difference. Drugs that are only mildly effective (3-5%) can be statistically significant and thereby approved by the FDA in America. Doctors should be prescribing lifestyle changes rather than drug treatment plans. It's more common in America for your physician to get out the prescription plan if you have high blood pressure. My point is, so what if there is a genetic difference. A lifestyle change swamps any small effect of genetics. Sadly, in America, drug researchers for drug companies tend to ignore the comparison to lifestyle changes so as to promote a drug that can earn a company billions of dollars annually. Sadly, the FDA and other agencies are asleep at the wheel.

African Americans are descended from groups that lived inland and had evolved to retain sodium, since they had little or no access to seafood as a source of salt. Living in the US on the modern high salt diet, they now have this protective sodium retention mechanism working against them.

I don't think you understand correctly what independent/dependent means here.

So things like race, income level, location, gender, age, and ethnicity would most likely be INDEPENDENT variables. And for the dependent one being heart disease, you could formulate hypotheses relating the risk of heart disease to each of the independent variables I listed. Keep in mind you'd next have to either conduct experiments to confirm/dispute your hypotheses or look up data on the exact same theories, as they're called in studies, in journals such as JAMA (Journal of the American Medical Association) or at AHA's website (American Heart Association). As for lifestyle, that varies and can actually be a dependent variable, so unless you simplify that to TYPE of lifestyle like active, less active, rarely active, or sedentary, it wouldn't work here- too complex to analyze this way. You can also do lifestyle based solely on diet type- Mediterranean, Chinese, Indian, junk food, healthy diet, vegan, vegettarian, low carb, low cal, low fat, etc. Hope this helps.

The independent variable needs to have a causal effect on the dependent variable. Here the variables you list as candidates for the dependent variable look more like independent variables to me. If your paper is on heart disease and your unit of analysis is communities, your dependent variable needs to be something about heart disease that varies across communities. It could be the proportion of people living in the community with heart disease, it could be the number of ambulance runs in a year for heart attacks. Just think of some variable that serves as an indicator or proxy for heart disease at the community level. Once you have that, think about the factors that you believe influence the dependent variable that you chose. Remember, since you are studying communities, that set of independent variables needs to be community-level variables. It could be the proportion of people in the community who smoke, or who drink coffee, or who don't exercise, or whatever makes sense in your field. Good luck.
