Cardiologist Serving Katy, Sugar Land, Greater Houston
Heart disease symptoms can appear gradually or suddenly and should never be ignored.
Heart disease is one of the most common health conditions affecting adults, and it can develop silently before noticeable symptoms appear. While some people experience chest pain or shortness of breath, others notice fatigue, dizziness, an irregular heartbeat, swelling or reduced exercise tolerance. At Advanced Cardiology, Dr. Khalid evaluates these symptoms and recommends testing when it is likely to help find the cause.
Call 911 for chest discomfort that lasts more than a few minutes or goes away and comes back; shortness of breath; discomfort in the arms, back, neck, jaw or stomach; a cold sweat, nausea or lightheadedness; fainting; or stroke signs such as face drooping, arm weakness or speech difficulty, even if they go away. Our offices are not emergency departments, and office messages and appointment requests are not for emergencies.
Many heart-related symptoms overlap with stress, aging, digestive problems or lung conditions, which is why a careful evaluation matters. Dr. Khalid combines your history, a physical examination and selected tests to determine whether symptoms are related to coronary artery disease, heart rhythm disorders, heart failure, circulation problems or another cause, including causes outside the heart.
Our focus is on timely diagnosis and preventive heart care, with individualized treatment plans designed to lower future risk and support long-term heart health.

Common Warning Signs of Heart Disease
Heart disease can affect blood flow, heart rhythm, circulation, and the heart’s ability to pump efficiently throughout the body. Symptoms may develop slowly over time or appear suddenly depending on the underlying condition. Some individuals experience obvious chest discomfort, while others may only notice subtle changes in breathing, energy levels, or physical endurance.
Common symptoms of heart disease may include:
Symptoms vary from person to person. Women, older adults and people with diabetes are more likely to have less typical symptoms such as fatigue, nausea or breathlessness. If any of these symptoms are sudden, severe, or occur with chest discomfort, fainting or trouble breathing, call 911. For symptoms that are mild, recurring or already checked for an emergency, schedule an evaluation.

Chest pain is one of the most recognized symptoms of heart disease, although not everyone experiences the same type of discomfort. People describe it as pressure, squeezing, heaviness, tightness, burning or aching.
Heart-related chest pain may:
Reduced blood flow to the heart muscle, called angina, is a common cause of chest discomfort linked to coronary artery disease. Chest discomfort that lasts more than a few minutes, comes and goes, occurs at rest, or is new or getting worse needs a 911 call rather than an office appointment, even if it does not feel severe.
Shortness of breath can occur when the heart cannot pump blood effectively or when fluid backs up into the lungs. Some people notice breathing difficulty during exercise, while others become short of breath when lying flat, wake up at night needing to sit up, or feel breathless at rest.
Fatigue and weakness may develop because the heart cannot deliver enough oxygen-rich blood to muscles and organs. These symptoms are associated with heart failure, coronary artery disease, arrhythmias, valve disease and weakened heart muscle, but lung disease, anemia and other conditions can cause them too. Learn more about shortness of breath evaluation. Sudden or severe breathlessness, or breathlessness with chest discomfort, needs a 911 call.
Abnormal heart rhythms, also called arrhythmias, may cause:
Some rhythm problems, such as atrial fibrillation, can increase the risk of stroke, while others are harmless. Because a brief office EKG may not capture symptoms that come and go, a wearable heart monitor is often used to record the rhythm during symptoms. Persistent or recurring symptoms should be evaluated by a cardiologist; see palpitations and irregular heartbeat care. Fainting, or palpitations with chest pain or shortness of breath, needs a 911 call.
Evaluation begins with a conversation about your symptoms, history, medicines and risk factors, followed by a physical examination. An EKG may be done in our office. Depending on your symptoms, Dr. Khalid may recommend an echocardiogram, a stress test, a wearable heart monitor, blood tests or cardiac imaging, which are performed or arranged by our office. Each test answers a different question, and none shows everything: an EKG captures only a few seconds of rhythm, an echocardiogram does not show the coronary arteries, and a stress test can miss some blockages. If a hospital procedure such as cardiac catheterization is needed, it is scheduled at an affiliated hospital. Dr. Khalid explains your results and the next steps in plain language.

Common symptoms include chest pain, shortness of breath, fatigue, irregular heartbeat, dizziness, and swelling in the legs or feet.
Yes. Reduced blood flow and weakened heart function may cause persistent fatigue and weakness.
No. Chest discomfort may also come from muscles, lungs, digestive issues, or anxiety, but cardiac causes should always be ruled out.
Yes. Conditions such as heart failure and coronary artery disease can reduce circulation and oxygen delivery.
EKG, echocardiogram, stress testing, Holter monitoring, and cardiac imaging are commonly used.
Yes. Arrhythmias and abnormal heart rhythms may indicate underlying cardiovascular problems.
Schedule a cardiology visit if symptoms are recurring, gradually worsening or interfering with daily activities, or if your doctor or a test result suggests a heart problem. Call 911 instead for chest discomfort lasting more than a few minutes or that comes and goes, fainting, sudden shortness of breath or stroke signs.
Yes. Swelling can occur when the heart does not pump effectively and fluid builds up, but it can also come from vein problems, kidney or liver disease, or some medicines. Swelling in one leg that is painful, warm or red should be checked promptly because it can signal a blood clot.
Yes. Some patients have silent heart disease that is only discovered during testing or after complications occur. That is why managing blood pressure, cholesterol, blood sugar and smoking matters even without symptoms.
