Cardiology

What we do

The Department of Cardiology at Kameda Medical Center provides care 24 hours a day, 365 days a year. We offer advanced treatments for many heart and blood vessel conditions, including emergency situations.
Most treatments are performed using catheters—thin tubes that can be guided through blood vessels. As technology improves, catheter procedures allow us to treat many conditions that once required major surgery.
We also specialize in catheter treatment for heart rhythm problems (arrhythmias). With the support of our anesthesiology team, these procedures can be done safely and comfortably under general or intravenous anesthesia.

Specialized Outpatient Clinic for Treatment-Resistant Hypertension

About each condition
Heart failure:
Heart failure often starts with shortness of breath. Other common symptoms include swollen legs, unusual fatigue, sudden weight gain (often due to swelling), palpitations, persistent coughing, and wheezing similar to asthma.

Heart Failure

Angina:
Angina often feels like pressure or tightness in the center of the chest or upper stomach area. The pain may spread to the neck, shoulders, arms, back, or jaw—this is called “radiating pain.”
Especially if the pain is accompanied by cold sweat, it may be a sign of a serious heart condition.
Symptoms usually worsen with exercise and improve with rest, but in severe cases they can occur even when resting.

Myocardial infarction:
Heart attack symptoms similar but are stronger and more sudden than those of angina. Because heart attacks can be life‑threatening, please call an ambulance immediately if you suspect one.

Arrhythmia:
Palpitations are the most common symptoms, but some people also experience dizziness, shortness of breath, or fatigue. The pulse may feel irregular, unusually slow, or very fast.
Because arrhythmias are often only detectable when symptoms are present, we recommend seeing a doctor promptly if you notice these signs.

Arrhythmia and Atrial Fibrillation

Catheter Ablation for Atrial Fibrillation

Saving Lives from Ventricular Tachycardia and Ventricular Fibrillation

Examination and Treatment of Premature Ventricular Contractions

Palpitations and Paroxysmal Suprasternal Tachycardia

Valvular heart disease:
As this condition progresses, symptoms similar to heart failure may appear. However, many people have no symptoms and are first diagnosed during a health checkup when a heart murmur is detected.
Early evaluation is important, so if a murmur is found during a checkup, please consult a doctor.

Cardiomyopathy:
Changes in the heart muscle can lead to heart failure symptoms including shortness of breath, swelling, or fatigue. Abnormal findings on an ECG or echocardiogram often reveal this condition.
Because treatments differ depending on the cause, please see a doctor if you have symptoms.

Cardiac Amyloidosis

Peripheral artery disease:
PAD occurs when arteries in the legs become narrowed or blocked. Pain in the legs—especially the calves—can appear while walking and improve with rest.
In advanced cases, people may feel pain even at rest, and small wounds on the toes may not heal easily.
If untreated, the condition can become severe, so early medical care is important. Congenital Heart Disease: You may be born with a hole in your heart, or a hole that was supposed to close at birth may remain open. Sometimes it is not noticed during childhood and is discovered in adulthood, or it may put a strain on the heart as an adult and require treatment. Our hospital also provides catheter treatment for adult congenital heart disease.

Atrial Septal Defect (ASD) and Catheter Closure

Cardiovascular diseases are often characterized by their urgent nature. Although appointments are generally required, we accept new patients at the clinic every weekday. In case of an emergency, care is available through our emergency department, so please contact us.
