I would like to take this opportunity to thank my Malaysian friend and gracious host, Bayi, and his wonderful, kind wife, Sok Kin, for the warm welcome, good food, great gifts, and tour my soulmate and I thoroughly enjoyed during our brief stay in Kuala Lumpur. Malaysia is a wonderful country. The progress I saw there confirms the vision its leaders have in seeing that country transform from developing to a fully developed country by 2020. Putrajaya, for example, where Bayi and his wife toured us, is wonderful city within a city. It houses the government's main agencies and boasts of impressive bridges and infrastructures one would only see in a first-world country.
Go and visit Malaysia if you have time, and see what you have been missing. For photos, you may refer to SIGHTSEER from time to time.
Back to the main program. I see that Bayi has placed a query in my message box below and I'd like to answer it now. He asks:
what is pulmonary hypertension compared to the normal use of the term "hypertension?"
Hypertension is your basic high blood pressure. When a doctor or nurse places a cuff on your arm and they get a blood pressure reading in the range of 140-160/90-100, that is a clear hypetensive reading. Pressure comes from the force of blood pushing against blood vessel walls. If the blood vessels are clear with no blocks like fatty deposits, then the sole pressure comes from the force of the heart as it pumps blood throughout the body. The causes of hypertension or high blood pressure are many and varied. A thorough physical and diagnostic examination coupled with a good clinical history can uncover the real cause(s) of any abnormal blood pressure reading.
Pulmonary hypertension, on the other hand, is high blood pressure limited to the arteries that supply the lungs. The main artery involved is the pulmonary artery which carries blood from the right ventricle of the heart to the lungs for oxygenation. How do you know you have pulmonary hypertension? To be accurate, a doctor might perform a right heart catherization in order to find out. Like basic hypertension, the causes of pulmonary hypertension are many and varied. A comprehensive clinical examination is needed to know the true cause(s).
