Causes of Hypertension
There are different risk factors for primary and secondary hypertension.
Primary Hypertension
Risk factors for primary hypertension include:
- Advancing age: Risk increases as people get older.
- Ethnicity: Certain populations, such as African-Americans, are at greater risk of developing high blood pressure at a younger age than other populations.
- Excess stress
- Excess weight
- Family history of hypertension
- Lack of regular exercise
- Tobacco use
- Too little potassium in the diet
- Too much salt or alcohol in the diet
Secondary Hypertension
Risk factors for secondary hypertension include:
- Adrenal disease
- Drugs
- Endocrine disease, such as thyroid and parathyroid disease
- Genetic diseases
- Kidney disease
- Metabolic problems
- Neurological diseases
- Pregnancy
- Renovascular hypertension: Narrowing of the vessels that supply the kidneys with blood
- Toxins
- Vascular disease (affecting blood vessels)
Diagnosis
Although hypertension usually has no signs or symptoms, it increases the risk of coronary heart disease, heart attack, and stroke. People can know if they have high blood pressure by having it checked regularly by their health care provider.
UT Southwestern cardiologists evaluate patients’ elevated blood pressure levels to determine the severity of the hypertension and whether it is primary or secondary hypertension.
As part of this evaluation, our physicians also review the medications patients are taking because some can negatively affect blood pressure and blood pressure medications.
Depending on the severity and type of hypertension, the UT Southwestern doctor might order additional testing to identify the cause of the problem and determine if the hypertension damaged the kidneys or heart. Additional tests might include:
Treatments for High Blood Pressure
We offer a number of treatments and strategies for managing hypertension, such as:
- Diet modification recommendations: Patient-specific advice about the types and amounts of food and drink to consume to lower blood pressure
- Exercise recommendations: Realistic, practical regimens that take into consideration each patient’s age and general health
- Medication: When diet and exercise alone don’t lower blood pressure, a medication program is specifically tailored to each patient. While a single medication might be effective, a combination of medications is sometimes the best solution.
Support Services
UT Southwestern’s cardiac rehabilitation specialists create customized plans that integrate proper nutrition, exercise, and, if necessary, nicotine cessation into patients’ lifestyles to improve their cardiovascular health.
Clinical Trials
As one of the nation’s top academic medical centers, UT Southwestern offers a number of clinical trials aimed at improving the outcomes of patients with cardiovascular disease.
Clinical trials often give patients access to leading-edge treatments that are not yet widely available. Eligible patients who choose to participate in one of UT Southwestern’s clinical trials might receive treatments years before they are available to the public.
