The proponents want to be clear though that it is still unclear how subfertility makes one more prone to cardiovascular problems. It still needs to be established what in subfertility makes women more prone to cardiac problems.

The researchers looked into the causes of a long road to pregnancy and factor in thyroid problems, obesity, and menstrual period irregularities. Women who have polycystic ovaries also tend to develop high cholesterol levels, hypertension, and increased level of blood sugar which are all contributing factors to heart problems.

The experts also looked into previous studies on subfertility and its connection to heart disease done previously. One study done to more than 860,000 women in Sweden between the early 1980’s thru 2005 looked into subfertility and heart disease in these women who might have been hospitalized or had a stroke, heart failure, or heart attack.

In the previous study, about 3,300 subjects ended up having heart problems. The number of heart disease cases on this population of subjects was also higher on those who encountered difficulty getting pregnant compared to those who did not have fertility problems.

The study was also able to conclude that subfertile women who got pregnant in 4 years or even less are not more prone to heart diseases. The higher risk is not that significant but the researchers suggest that women should seek consult and have regular checkups.

The proponents of the study are also worried about the doubling of the percentage of people who have triglycerides in just 30 years. This may be attributed to the increased levels of obesity in the population.

The CDC is looking into possible ways to address the problems as other studies point out to only a fraction of these people with high blood fats taking medication and other steps to take care of their health.

Like LDL or bad cholesterols, triglycerides makes one prone to heart attacks. People with LDL take statins to lower their levels but this medicine is not very effective in lowering the levels of triglycerides. Triglycerides may come from fats in the body and fats of the food that people eat.

Blood samples of 5610 people who are 20 years or older were studied. During the 1999 to 2004 survey, 33.1% of the population were positive for high triglyceride levels measured at 150-199 mg/dL or interpreted as borderline high.

Around 18 per cent of the subjects were considered to have high levels of triglycerides or a reading of 200 mg/dL or higher. About two percent of the participants had a reading of 500 mg/dL.

Higher readings of triglycerides were taken from older whites who declared positive history of smoking, were obese, and had less than 2.5 hours of exercise per week. They found out that women had lower risks. Mexican and African-Americans had lower risks than whites.

Treatment guidelines may be revised as more and more data help doctors in establishing the link to bad blood fats and heart attack which is the leading cause of death in the United States.
