Cardiologist Serving Katy, Sugar Land, Greater Houston
Advanced care for hypertension, elevated blood pressure, circulation concerns, and long-term heart health management.
High blood pressure often develops without noticeable symptoms. You may feel well while elevated pressure gradually places stress on your blood vessels, heart, brain, kidneys, and other organs.
At Advanced Cardiology, Adnan Khalid, MD, provides outpatient evaluation and ongoing treatment for adults with newly diagnosed, uncontrolled, or difficult-to-manage high blood pressure. Appointments are available at our Sugar Land office at 7102 Tarrington Ave, Suite 505. For a general overview of the condition, read our hypertension (high blood pressure) guide.
Your evaluation is based on accurate blood pressure measurements, your medical and family history, current medications, cardiovascular risk, previous test results, and individual treatment needs. Not every patient requires the same tests, medications, or blood pressure target.

Understanding your numbers
Blood pressure is the force of blood pushing against the walls of your arteries.
A blood pressure reading contains two numbers:
High blood pressure, also called hypertension, is diagnosed when properly measured readings remain above the healthy range over time. One elevated reading does not necessarily establish a diagnosis. Confirmation usually involves repeated office readings and may include home or ambulatory monitoring.
Category | Systolic pressure | Diastolic pressure |
Normal | Less than 120 | And less than 80 |
Elevated | 120–129 | And less than 80 |
Stage 1 hypertension | 130–139 | Or 80–89 |
Stage 2 hypertension | 140 or higher | Or 90 or higher |
Severe hypertension | Higher than 180 | And/or higher than 120 |
These categories help guide evaluation, but a clinician must interpret your readings in the context of your health, medications, age, cardiovascular risk, and measurement conditions. The 2025 AHA/ACC guideline generally supports a treatment goal below 130/80 mm Hg for adults with hypertension, while recognizing that some patients require individualized goals.

Hypertension is sometimes described as a “silent” condition because most people do not feel when their pressure is elevated.
Headaches, fatigue, dizziness, facial flushing, or nervousness are not reliable ways to determine whether your blood pressure is high. The only way to know your numbers is to measure them correctly.
Symptoms become especially concerning when they occur with a very high reading. If a repeat reading stays above 180/120 and you have chest pain, breathlessness, back pain, weakness, numbness, vision changes or difficulty speaking, call 911; this may indicate organ injury. Chest discomfort lasting more than a few minutes and stroke signs (face drooping, arm weakness, speech difficulty) need a 911 call at any blood pressure, even if they go away.
Persistently elevated pressure can damage arteries and make the heart work harder. Over time, uncontrolled hypertension can increase the risk of:
Treatment is intended to reduce these long-term risks—not simply to produce a lower number during one office visit.
Primary-care clinicians successfully manage many uncomplicated cases of hypertension. A cardiology consultation may be particularly useful when blood pressure is difficult to control or occurs with known or suspected cardiovascular disease.
Consider discussing a cardiology referral or appointment when:
Do not schedule a routine appointment for active emergency symptoms. Call 911 when high blood pressure occurs with chest pain, difficulty breathing, neurological symptoms, fainting, or other warning signs.
Resistant hypertension is high blood pressure that remains above the recommended goal despite treatment with three appropriately selected blood pressure medications, generally including a diuretic, or blood pressure that requires four or more medications to control.
Before labeling hypertension as resistant, a clinician should consider whether:
This evaluation is important because an apparently resistant reading can sometimes reflect a measurement problem, a white-coat effect, medication interactions, or an underlying treatable condition.
Most adults have primary hypertension, which tends to develop gradually through a combination of age, genetics, lifestyle, environment, and cardiovascular risk factors.
Factors associated with increased risk include:
Secondary hypertension is caused or worsened by another medical condition, medication, or substance.
Potential contributors may include:
Do not stop a prescribed medication on your own. Bring a complete list of prescriptions, over-the-counter medicines, vitamins, supplements, energy products, and other substances to your appointment so the cardiologist can review possible effects and interactions.
Blood pressure can be affected by:
The cardiologist may repeat the measurement using standardized technique and compare office readings with measurements taken outside the office.
Home readings can help identify:
Your consultation may include questions about:
Blood pressure treatment decisions are not based only on one number. The cardiologist may consider your overall likelihood of heart attack, stroke, heart failure, and other cardiovascular complications.
Current guidelines use factors such as existing cardiovascular disease, previous stroke, diabetes, chronic kidney disease, and estimated cardiovascular risk when deciding how quickly medication should begin and how intensive treatment should be.
Long-term hypertension can affect the heart, kidneys, arteries, brain, and eyes. The cardiologist will decide whether additional laboratory work, cardiac testing, or coordination with another specialist is appropriate.
Targeted evaluation may be recommended when hypertension:
The 2025 hypertension guideline places renewed emphasis on recognizing secondary conditions, including primary aldosteronism, obstructive sleep apnea, kidney disease, and renovascular disease.
Not every patient needs every test. Dr. Khalid may recommend or coordinate testing based on your readings, medical history, cardiovascular risk, examination, medications, and previous results.
Repeat measurements help determine whether the elevation is persistent and whether the treatment plan is working.
A structured home log can help confirm the diagnosis, assess control, and compare home and office readings.
A portable monitor can record blood pressure throughout the day and night. It may be helpful when white-coat or masked hypertension is suspected or when blood pressure varies substantially.
Testing may be used to assess:
The 2025 guideline added greater emphasis to urine albumin-to-creatinine testing as part of the initial evaluation of adults with hypertension.
An EKG or ECG, performed in our office, records the heart’s electrical activity. It may identify rhythm abnormalities or patterns suggesting that hypertension has affected the heart, but it cannot measure wall thickness or pumping function directly.
An echocardiogram, performed or arranged by our office, uses ultrasound to evaluate heart structure, wall thickness, pumping function, and heart valves. It may be recommended when symptoms, examination findings, an abnormal EKG, or another clinical concern suggests that additional structural information is needed.
An echocardiogram is not automatically required for every person with high blood pressure.
Screening or sleep evaluation may be considered when hypertension occurs with:
Depending on the clinical findings, testing may include hormone studies, an aldosterone-renin assessment, kidney imaging, renal-artery evaluation, or another targeted investigation.
Treatment is based on your average readings, cardiovascular risk, other medical conditions, medication tolerance, and personal treatment goals.
A care plan may include lifestyle changes, medication, home monitoring, follow-up appointments, and treatment of an underlying condition.
The 2025 AHA/ACC guideline supports a general treatment target below 130/80 mm Hg for adults with hypertension, but the safest goal may be individualized for people who are frail, pregnant, receiving institutional care, experiencing medication side effects, or living with other significant medical conditions.
Recommended changes may include:
People with kidney disease or certain medications should ask their clinician before substantially increasing potassium or using potassium-containing salt substitutes.
Medication may be recommended in addition to lifestyle changes.
Current guidance generally recommends medication for adults with an average pressure of 140/90 or higher. Medication may also be recommended at 130/80 or higher when a person has cardiovascular disease, previous stroke, diabetes, chronic kidney disease, or increased predicted cardiovascular risk. Lower-risk patients whose pressure remains at or above 130/80 after a lifestyle trial may also need medication.
Common first-line medication groups include:
The most appropriate choice depends on kidney function, potassium level, age, pregnancy status, other cardiovascular conditions, previous reactions, drug interactions, and individual tolerability.
Different blood pressure medicines work in different ways. Some patients—particularly those with stage 2 hypertension—may benefit from beginning two compatible medications. A single combination pill may make the treatment plan easier to follow when clinically appropriate.
It can take time to identify an effective and well-tolerated treatment plan. Follow-up may include:
Do not stop, reduce, double, or otherwise change a blood pressure medicine without instructions from your healthcare professional. A normal home reading may mean the treatment is working; it does not necessarily mean the medication is no longer needed.
Home monitoring is most useful when the equipment and technique are reliable.
Use:
Wrist and finger monitors are generally less reliable. Bring your monitor to an appointment so the care team can compare it with office equipment and check your technique.
For 30 minutes beforehand:
Empty your bladder and sit quietly for at least five minutes.
Take two readings approximately one minute apart and record both. Measure at the times recommended by your clinician rather than checking continuously because of anxiety.
Record:
Bring the record and your monitor to your appointment.
Do not substitute a smartwatch or another cuffless device for a validated upper-arm monitor unless your clinician has specifically confirmed that the device is appropriate. The 2025 guideline advises against relying on cuffless devices for accurate clinical blood pressure measurement until their reliability improves.

Primary-care physicians, family-medicine clinicians, internists, cardiologists, kidney specialists, and other qualified clinicians can treat hypertension.
A cardiologist may be particularly appropriate when blood pressure is difficult to control, several medications are required, cardiovascular disease is present, or the patient has symptoms or tests suggesting that hypertension has affected the heart.
Cardiologists are trained to diagnose and manage cardiovascular conditions, including hypertension and its effects on the heart and blood vessels.
Some clinicians also hold a separate hypertension-specialist certification. At Advanced Cardiology, Dr. Khalid manages high blood pressure as a cardiologist, with particular attention to how it affects the heart and blood vessels.
For adults, stage 1 hypertension begins at a systolic pressure of 130–139 or a diastolic pressure of 80–89. Stage 2 hypertension begins at 140 systolic or 90 diastolic.
A diagnosis should be based on repeated, properly measured readings—not one isolated number.
Most hypertension causes no noticeable symptoms. A person can have elevated pressure for years without realizing it.
Symptoms such as chest pain, shortness of breath, weakness, numbness, vision change, or difficulty speaking are particularly concerning when the pressure is above 180/120 and require a 911 call. Chest discomfort lasting more than a few minutes or stroke signs need 911 at any reading.
Wait at least one minute and take the measurement again using proper technique.
Call 911 when the repeated reading remains that high and you have chest pain, shortness of breath, back pain, numbness, weakness, vision changes, trouble speaking, or another new concerning symptom.
When the repeated reading remains above 180/120 without symptoms, contact your healthcare professional promptly for instructions. Do not adjust your medication without medical guidance.
A temporary increase can be associated with stress, pain, illness, caffeine, nicotine, exercise, poor sleep, a full bladder, an incorrectly sized cuff, missed medication, or certain medicines and supplements.
Sudden severe hypertension can also reflect a more serious problem. Repeat the reading correctly and follow the emergency guidance above when the measurement remains very high or symptoms are present.
Resistant hypertension generally means blood pressure remains above goal despite three appropriately selected medications or requires four or more medications for control.
The evaluation may include confirming home readings, reviewing medication use and interactions, and looking for causes such as sleep apnea, kidney disease, or primary aldosteronism.
Anxiety and stress can temporarily increase blood pressure. Nervousness in a medical office may also produce higher office readings, sometimes called a white-coat effect.
Anxiety should not automatically be assumed to be the explanation for persistent or severe readings. Home or ambulatory monitoring may help show whether blood pressure remains elevated outside the office.
Yes. Some decongestants, nonsteroidal anti-inflammatory medicines, stimulants, sodium-containing products, supplements, and other substances can raise blood pressure or interfere with treatment.
Ask a clinician or pharmacist before starting an over-the-counter medicine or supplement when you have hypertension.
Upper-arm cuff monitors are generally preferred. Wrist and finger monitors can be more sensitive to positioning and may produce less reliable readings.
Use a validated automatic upper-arm monitor with a properly fitting cuff unless your healthcare professional recommends a different device.
No. The decision depends on the average blood pressure, cardiovascular risk, and other medical conditions.
Lifestyle changes are recommended for adults with elevated pressure or hypertension. Medication is generally recommended at 140/90 or higher and may be recommended at 130/80 or higher when cardiovascular disease, previous stroke, diabetes, kidney disease, or increased predicted risk is present.
Yes. A heart-healthy eating pattern, lower sodium intake, regular activity, healthy weight, improved sleep, limited alcohol, tobacco cessation, and stress management can improve blood pressure.
Lifestyle changes should complement rather than replace medication when medication is medically indicated.
Do not stop medication without speaking with your healthcare professional. A normal reading may mean the treatment is working.
Stopping suddenly can allow blood pressure to rise and may be unsafe with certain medications.
The current general treatment goal is below 130/80 mm Hg for most adults with hypertension. Your individual target may differ based on your overall health, medication tolerance, pregnancy status, frailty, and other medical considerations.
Most major insurance plans are accepted, and coverage is verified individually. Because networks, referral rules and benefits can change, call (713) 258-6111 before your appointment to confirm coverage and any authorization requirements.
High blood pressure management should be based on accurate readings, your overall cardiovascular risk, and a treatment plan you can follow safely.
