How Does High Blood Pressure Cause Heart Attack

Heart attack is called as Myocardial Infarction in medical terminology. Heart is supplied by right and left coronary arteries. Whenever these arteries are blocked, blood supply to heart stops and wall of heart damages, result is Heart Attack with symptoms of severe constricting chest pain radiating to left arm jaw or shoulder, profuse sweating, vomiting, and feeling of anxiety. If the blood supply is cut off for more than a few minutes, muscle cells suffer permanent injury and die. This can kill or disable someone, depending on how much heart muscle is damaged.

There are 4 major risk factors which are responsible for this heart attack. What are those? Hypertension also called as High Blood Pressure, Hypercholesterolemia, Diabetes, and Smoking. In this article our main focus is High Blood Pressure. How does High blood pressure play role in causing Heart Attack. Remember, whenever coronary blood supply will be decreased or blocked, heart attack will take place. Arteries can be blocked by two different ways. Atherosclerosis and second cause is Artery spasm. Now lets discuss process of Atherosclerosis.

Atherosclerosis is a type of arteriosclerosis. The name comes from the Greek words athero (meaning gruel or paste) and sclerosis (hardness). It is a process of formation of plaque inside the wall of blood vessel. Plaque is collection of fatty substances, cholesterol, cellular waste products, calcium and fibrin (a clotting material in the blood). When person gets old, process of atherosclerosis starts. Thickening of blood vessels is called atherosclerosis. So far we have just talked about thickening of vessels. How vessels get block.

Now what next, plaque can undergo following changes. Either bleeding (hemorrhage) into the plaque , blood enters into wall of blood vessel, thus it gets more thickened and block the vessel or plaque gets damage and platelet(Cells which helps in clotting process) comes and aggregate on the plaque where it damages. Thus causing more narrowing of vessel. We were talking about blood pressure causing atherosclerosis. Yes, it is main risk factor. Actually it is high blood pressure which causes injury to these plaques, so after injury to these plaques, platelet comes to injured areas and further narrow the blood vessels.Because of the damage, over time fats, cholesterol, platelets, cellular debris and calcium are also deposited in the artery wall. These substances may stimulate the cells of the artery wall to produce still other substances like smooth muscles. This results in more cells accumulating in the innermost layer of the artery wall where the atherosclerotic lesions form. These cells accumulate, and many of them divide. At the same time, fat builds up within and around these cells. They also form connective tissue.

Atherosclerosis affects large and medium sized arteries. The type of artery and where the plaque develops varies with each person.Atherosclerosis is a slow, progressive disease that may start in children as well. In some people this disease progresses rapidly in their third decade. In others it doesn't become threatening until they're in their 50s or 60s.

If atherosclerosis takes place in heart vessels -- oxygen supply to the heart muscles decreases, resulting in heart wall damage, called as Heart Attack.

Second cause of decreased blood supply is artery spasm. Sometimes a coronary artery temporarily contracts or goes into spasm. When this happens the artery narrows and blood flow to the heart muscle decreases or stops. A spasm can occur in normal-appearing blood vessels as well as in vessels partly blocked by atherosclerosis. A severe spasm can cause a heart attack.

So always keep your blood pressure under controlled limits, otherwise you can be a victim of Heart Attack.

I Finally Took Guitar Lessons
I have a huge list of goals that I want to achieve during my life time. Some goals are small like learning to keep a goldfish alive for longer than a month. Other goals are more significant like traveling to all fifty states or learning a second language. As I continue to learn new things and accomplish goals on my list it seems that I also add new goals to my list so that it never gets much smaller or much bigger. I think I'll always have more goals than I can accomplish. I recently accomplished a goal that has been on my list since its beginning. I started taking guitar lessons.

Sound like no big deal? If it doesn't, then you obviously do not know me well. You have no idea that I have wanted to learn how to play guitar since I was eight and you have no clue that I have been saving my spare change for years to buy a guitar and begin taking lessons. You see, for me, starting guitar lessons was the sign of so many other things that had happened in my life.

Starting guitar lessons was a sign that I had been faithful to save spare change for over six years and it was a sign that I finally got up the courage to do something I am not good at. I have this tendency to only spend time on things I can do well at, so most of the goals on my list that involve learning new skills get left undone. So it was a real feat for me to begin guitar lessons. My first lesson symbolized my desire to stop living afraid of things that cannot hurt me. Guitar lessons are the first step in a direction I have been wanting to head for quite some time.

Starting guitar lessons has also helped me to cross off another goal from my list: getting over my fear of meeting and spending time with new people. The man who is giving me guitar lessons could probably go down in history as one of the least intimidating people on the earth, yet it is still significant for me to have taken this step. I will never forget the feeling of anxiety I felt as I knocked on his front door on the afternoon of my first lesson. I felt like my heart was going to pound out of my chest. Within five minutes I had entered his house, learned a little about him, began my first of many guitar lessons, and could cross off two goals on my list at the same time. Not bad for just five minutes.

Acne Review Treatment - The New Face Of Benzoyl Peroxide
One of the problems with benzoyl peroxide topical acne treatments is that they can be quite irritating, particularly to sensitive skin. Those fans of benzoyl peroxide will thus be pleased to learn that one skin care company that supplies prescription acne and skin care products is releasing a treatment with a delivery system that reduces benzoyl peroxide's irritating effect.

Called NeoBenz Micro, this acne treatment will be available only by prescription, which is one drawback. On the plus side, it should mean that the acne sufferer is given the appropriate strength to their particular needs. It is aimed at helping people with mild to moderate acne, and comes in three strengths. These are 3.5% benzoyl peroxide, 5.5% benzoyl peroxide, and 8.5% benzoyl peroxide.

The difference in this treatment as compared to regular benzoyl peroxide solutions, is that it is a time release product. The method designed by SkinMedica, NeoBenz Micro's developer, uses very small 'sponges', called microsponges. These hold the active ingredient, in this case benzoyl peroxide, to be slowly released throughout the day. It means that though acne is kept in contact with benzoyl peroxide for the whole day, only small amounts of it are released onto the skin. These amounts are enough to be effective but far less irritating.

The side effects that this benzoyl peroxide acne treatment aims at reducing are rashes, skin soreness, and irritation. Aside from the unpleasant feeling these effects create, they unfortunately also reduce the effectiveness of benzoyl peroxide in clearing acne.

NeoBenz Micro is one example of a new trend in the pharmaceutical industry. It aims at taking existing products and developing new ways to package and deliver the active ingredients, thus effectively modernizing many treatments. The emphasis in the past had been more research oriented - finding new and more powerful treatments rather than fine tuning existing ones that were proven to work.

Other examples of this phenomena include converting treatments into sprays, with the effect of increasing absorption and convenience. MedPharm, a research contracting firm, is turning one eczema treatment and two acne treatments into sprays. These are still in the development stage, however.

My Rented Vacation - The RV Saga
My wife and I have a tradition of vacationing the month of January at a quaint little area in Florida. It is not on the beach where the high priced restaurants are located and where the crowds gather. We enjoy this quiet little RV park that is on the banks of a fishing lake located in central Florida. Several couples caravan south in our RVs to escape the harsh winter weather which seams to get worse the older we get. It is a time that we can relax after the busy holiday season and we can renew our close relationships with our friends.

This year we ran into some bad luck just before we were to depart for our relaxing getaway. The RV would not start and it needed engine repairs that would not be finished in time for our vacation. We did not want to cancel our plans, as this time is something that we look forward to each year. So we decided to rent an RV for our trip.

There are a couple of dealers close that have RV motorhome rentals available, so we decided to check them out. The first question that we were asked was if this was a one way RV rental. I answered no, and that we would be returning in it. They mentioned that they were a pet friendly RV rental agency and did we have pets. My answer again was no, and we would rather not rent a motorhome that pets have inhabited. My wife is allergic to pets. They were very friendly and helpful and seemed to the RV motor home rental business very well.

I was very much impressed when they suggested that we drive to Florida in our automobile and rent an RV unit when we get there. This would save us several dollars in fuel expenses, enough to where we could afford a motel if need be. My one concern was if there would be a unit available to rent when we got there. And being the professionals that they are, they went ahead and made all of the necessary arraignments for us. They secured a vehicle for us that would be waiting, ready to go, when we arrived in Florida, and helped us make the deposit online.

So we didn’t miss our January outing after all, and it ended up being a very memorable occasion. I will not forget our rented vacation. When we returned from our trip, I purchased a new vehicle from the dealer with the friendly and very helpful rental staff.
