Men who suffer from HIV or Human Immunodeficiency Virus experience many health disadvantages. Not only do they have weaker immune system, but they are also known to be more susceptible to heart attacks when compared to people who do not suffer from HIV.
HIV is a lentivirus (slowly-replicating retrovirus) that causes acquired immunodeficiency syndrome (AIDS), a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells.
HIV is a virus that is capable to destroy the immune system of the sufferers. This virus is what later is able to lead to AIDS. HIV can be transmitted through sexual contact, blood, or passed on from a mother to her baby. There are several symptoms of HIV which are weakness, diarrhea, fever, headache, muscle or bone pain, or sores on the lips, and vaginal yeast infections.
HIV itself, believed to have originated in non-human primates in West-central Africa and to have transferred to humans (a process known as zoonosis) in the early 20th century.
In the research done here, researchers of this study conducted a study on 82,459 subjects, in which 27,350 of whom had HIV. The participants of this study were observed for 5.9 years. During the study, approximately 871 participants experienced a heart attack. About 176 heart attacks that occur were quite fatal. Meanwhile, 42 percent of heart attacks occur in people who has HIV.
When researchers involved calculating other risk factors such as blood pressure, diabetes, drugs, and alcohol, subjects with HIV still had a 48 percent higher risk for heart attack when compared to people who do not have HIV.
Because the participants who took part in the study were men, the researchers do not yet know about the increased risk of heart attacks possibility in women with HIV. This is as reported by CBS News (05/03).
Lead author Dr Matthew Freiberg, who is a professor at the University of Pittsburgh School of Medicine in Pennsylvania explained that the researchers do not know clearly why HIV patients have a greater risk of heart attack. The possibility of this is caused by medicines taken by patients with HIV and a weak immune system that cause inflammation in the body.
In a previous research, it was stated that HIV drugs does not cause heart attacks.
