Understanding Heart Disease

Heart disease is a condition of heart disorder experiencing interference. The form of disorder itself can vary. There are disturbances in the heart's blood vessels, heart rhythm, heart valves, or congenital disorders born. The heart is a muscle that is divided into four spaces. Two rooms at the top are the right and left atrium. Two back spaces are located at the bottom, the right and left ventricle. Between the right and left chamber is separated by the muscular wall (septum) that serves to prevent the mixing of oxygen-rich blood with the blood of poor oxygen.

 The main function of heart is to drain oxygen-rich blood to all parts of the body. After all organs of the body use oxygen in the blood, the poor blood of oxygen returns to the heart (right atrium), to be forwarded to the right ventricle through tricuspid valve. After the blood meets the right ventricle, tricuspid valve will close the usefulness of preventing blood from returning to the right atrium. Then, when the right ventricle contracts, the poor blood of oxygen will appear from the heart through the pulmonary valve and the pulmonary artery, then brought to the lungs to be filled with oxygen. The blood that has been enriched by oxygen, after it is taken to the left atrium through the pulmonary vein. When the left atrium contracts, the blood is passed to the left ventricle through the mitral valve. Once the left ventricle is filled with blood, the mitral valve closes to prevent the blood from returning to the left atrium. Then, the left ventricle will contract, and the blood will be streamed to all the body through the aortic valve. The circulatory cycle will remain repetitive.




Types of heart disease
The term heart disease involves a wide range of disorders in the heart, among others:
Coronary artery disease (coronary heart disease) – narrowing of the heart blood vessels.
Arrhythmias – Disorders of the heart rhythm.
Congenital heart disease – heart abnormalities from birth.
Cardiomyopathy – disorders of the heart muscle.
Cardiac infections – infections of the heart due to bacteria, viruses, or parasites.
Diseases of the heart valve – disorders in one or four erroneous heart valves.

HIV And AIDS Prevention


Until this time, no vaccine was able to prevent HIV infection. However, infection is prevented by more than one of the following:


 Use a new condom every sex related, whether sex is through the vagina or through the anus. When deciding on a lubricant condom, make sure the lubricant is made of basic water. Avoid condoms with lubricants made from basic oil, because it is able to cause condoms leaked. For oral sex, take advantage of unlubricated condoms.
Avoid having sex with more coming from one partner. Tell your spouse if you are positive in HIV, so that your spouse has HIV test. Discuss with the doctor if you are diagnosed with HIV positive in pregnancy, regarding subsequent treatment and plan of childbirth, to prevent transmission from mother to fetus.
For men, it is recommended circumcision to reduce the risk of HIV infection.
Immediately to the doctor if it is suspected to have been infected with HIV, if it is related to sex with HIV sufferers. The Doctor is able to prescribe post-exposure prophylaxis (PEP) medication, to be consumed for 28 days. PEP drug is a combination of 3 antiretroviral drugs, which are able to prevent the growth of HIV infection. Nevertheless, the therapy with PEP must begin a maximum of 3 days after a viral infection occurs.


HIV And AIDS Treatment


Although until this time there is no cure for HIV, but there are medicine styles that are able to slow down the growth of viruses. This type of drug is called antiretroviral (ARV). ARV works together by discourage the elements that the HIV virus needs to multiply, and inhibit the HIV virus from destroying CD4 cells. Some of the ARV medicinal styles, among others:
Efavirenz
Etravirine
Nevirapine
Lamivudine
Zidovudine
While taking antiretroviral drugs, doctors will monitor the quantity of viruses and CD4 cells to assess the patient's response to treatment. Calculate CD4 cells will be done every 3-6 months. While the HIV RNA check is done since the beginning of treatment, continued every 3-4 months throughout the period of treatment.

Patients should immediately consume ARV so diagnosed with HIV, so that the growth of HIV virus is able to be controlled. Delay treatment will cause the virus to still cause damage to the immune system and increase the risk of HIV sufferers in AIDS attack. In addition, it is absolutely for patients to consume ARVS according to doctor's guidelines. Skipping taking the drug will cause HIV viruses to develop more rapidly and exacerbate the patient's condition. When the patient misses the schedule of consuming the drug, immediately drink so remember, and forever follow the next schedule. But suppose that the dose missed a lot, directly talk with the doctor. The Doctor is able to change the prescription or dose medication according to the patient's condition.
HIV patients include being able to consume more than 1 ARV drug in a day. Therefore, patients should understand the side effects arising from consuming this drug, including:
Diarrhea.
Nausea and vomiting.
Dry mouth.
Bone brittleness.
High blood sugar levels.
Abnormal cholesterol levels.
Muscle tissue Damage (rhabdomyolysis).
Heart disease.
Dizziness.
Headaches.
Sleeplessness.
The body feels tired.
