Statins and Heart Disease
Among the most common cholesterol-lowering drugs are statins. They are also known as HMG-CoA reductase inhibitors. They are used to lower LDL (bad) cholesterol and reduce the risk of atherosclerotic cardiovascular disease. These drugs also decrease the risk of mortality in high-risk patients.
Reduce atherosclerotic cardiovascular disease
Historically, statins have been viewed as lipid-lowering medications. However, recent clinical trial data suggests that they may actually increase the risk of NOD in a dose-dependent fashion. Until more robust trials are conducted, caution is in order.
The USPSTF recommends that adults with 1 or more CVD risk factors take a low- to moderate-dose statin. These recommendations do not apply to adults with an LDL-C level above 190 mg/dL.
The FDA recently announced that it has widened the label for a class of lipid-lowering drugs known as HMG inhibitors to include patients with dyslipidemia. These drugs should be tested for their pleiotropic effects. The most important question is not whether statins are effective lipid-lowering agents, but whether they are safe for the intended patient population.
Unlike the old cholesterol-lowering drugs, new lipid-lowering drugs have to be evaluated for their pleiotropic effects. The American College of Cardiology and the American Heart Association recently developed a guideline on the management of blood cholesterol. The ACC/AHA recommended the use of statins to lower triglyceride levels in patients with high-risk risk factors for cardiovascular disease. Those with dyslipidemia should be offered a low-to-moderate dose of statin.
The USPSTF’s corresponding recommendation is that adults with a 10-year CVD risk of greater than 20% should take a low-dose statin. The most important factor in the decision to reduce LDL-C with pharmacotherapy is the patient’s estimated 10-year CVD risk. This factor is best incorporated into a shared decision-making discussion between the patient and provider. The benefits of statin are greatest for those at the highest risk.
There are plenty of statins to choose from. Ideally, the best statin is the one that is most likely to lower the patient’s LDL-C while avoiding unwanted side effects.
Lower triglycerides
Among the various drugs used to treat high triglycerides, statins are one of the most common. They are usually effective in reducing triglycerides. However, they may also cause some side effects.
A very high level of triglycerides is associated with the risk of developing a form of pancreatic inflammation known as acute pancreatitis. It is also associated with the risk of coronary heart disease. The primary goal of treating very high triglycerides is to prevent acute pancreatitis. In addition, the secondary goal is to lower the risk of CHD.
Other drug therapies include the use of insulin or a lipid-lowering drug. These treatments are generally cost-effective. They are also effective in treating patients with very high triglycerides.
Some patients may benefit from taking omega-3 fatty acids. These oils are found in certain fish. They are thought to help increase HDL-C in patients with low LPL levels. Niacin has been shown to raise HDL-C levels. But high doses of niacin may cause glycemic control problems in diabetics.
In the case of very high triglycerides, a very low-fat diet should be emphasized. Weight loss is also very effective in lowering triglycerides in overweight/obese individuals.
In addition to lowering triglycerides, statins may be helpful in lowering beta-VLDL, a type of cholesterol that carries triglycerides throughout the body. Fibrates are also effective in lowering beta-VLDL.
A combination of lipid-lowering therapy and exercise is the most effective way to treat high triglycerides. In addition, dietary modification may also be useful. A dietary plan that is low in fat and high in fiber, and primary fibrates, can be very effective in lowering triglycerides.
Several studies have shown that lowering triglycerides and increasing HDL-C is important in preventing or minimizing the risk of CHD. While lipid-lowering treatment is not without risks, it is considered very safe and generally cost-effective.
Interact with other medicines
Using statins to lower cholesterol and reduce heart disease risk is a great idea, but statins can sometimes interact with other medications. These interactions can be minimized by the co-administration of lipid-modifying medications. The best way to do this is to start out slowly with a lower dose of the statin.
Some drugs can actually interfere with the metabolism of statins. These include clot-preventing medications such as ticagrelor, dronedarone, and warfarin. Other common drugs that can interfere with statin metabolism include nicotinic acid, fibrates, and omega-3 ethyl esters.
The best way to mitigate these drug-drug interactions is to use clinical management strategies. These include the co-administration of lipid-modifying medications such as fenofibrate. The use of a calcium channel blocker such as amlodipine or verapamil can also reduce the risk of statin-induced toxicity.
The American Heart Association released a statement to help doctors navigate their medication choices. The most important part of the message is that the association has been clear about the fact that it is important to be aware of the possible interactions between statins and other medicines. These interactions are not necessarily the end-all and be-all of cardiovascular treatment, but they can be an opportunity for a physician to save a patient from a potential adverse event.
The best way to minimize this risk is to talk to your physician about all the drugs you are taking and to monitor your statin levels closely. The benefits of this approach far outweigh the potential risks.
The best way to know for sure is to make a list of all the medications you are currently taking, and then discuss them with your doctor. This will not only help you avoid unnecessary interactions, but it will also allow your physician to prescribe the most appropriate medicine for your individual needs.
Predict your chances of having a heart attack in the next 10 to 30 years
Having a heart attack at any age can be a serious threat to your health. While there are no guarantees, you can take certain steps to lower your risk.
For people with high cholesterol, doctors recommend taking statin drugs. They also recommend eating a healthy diet, quitting smoking, and being physically active. However, you should also discuss your risk with your doctor. If you have a family history of heart disease, you may need to take other preventive measures.
You can also use a calculator to estimate your risk. There are several tools online and in your doctor’s office. They will ask you for specific information, but there should be no major differences in the results. Some of these tools can calculate the risk for your whole family. You can also use a smartphone app to perform the same assessment. These tools consider your race, health condition, and other factors.
The American College of Cardiology (ACC) and the American Heart Association (AHA) recommends that all adults with risk factors for cardiovascular disease take low- to moderate-dose statins. If you have high cholesterol, you should also talk to your doctor about whether you should start taking aspirin.
The ACC/AHA risk estimator uses a combination of factors to predict your lifetime risk of having a heart attack. It includes your age, smoking status, diabetes, and other medical conditions. It has separate equations for men and women.
The US Preventive Services Task Force (USPSTF) has released the latest guidelines on the use of statins. Their recommendations are generally more conservative than those of the ACC/AHA. They recommend taking a low- to moderate-dose statin for adults aged 40 to 75.
