Personalised Treatment Plans

Dr Karagiannis offers patient-specific treatment for a variety of common health conditions, such as elevated blood pressure (hypertension), increased cholesterol (hyperlipidemia), heart rhythm problems (arrhythmias) and chest pain (coronary artery disease and angina). He also offers a personalised treatment plan for every patient, which is clearly documented and explained. His consultations are supplemented with video and other interactive media material, that will help you understand the nature of the problem and the management plan.

One-Stop Clinic

Dr Karagiannis understands that your time is precious and will therefore offer you an appointment for an initial consultation as soon as possible (usually within 2 days). He also runs one-stop clinics, where you can have both the consultation and the basic cardiac tests (ECG, Echocardiogram) on the same day. This will save you from having to go back and forth to the hospital.

One-to-One Contact

Dr Karagiannis believes in the value of continuous one-to-one contact between doctor and patient. Consultations are key since many conditions are only diagnosed once a thorough history is taken by a specialist. However, during your first consultation you will be given a contact number and e-mail address which you can use to contact Dr Karagiannis any time you want to ask any question regarding your care.

Are you experiencing any of these symptoms?

Symptoms, such as breathlessness on exertion, chest pain, palpitations/“fluttering” of the chest can be the first signs of heart disease. If you feel more breathless than usual climbing a set of stairs, if your chest hurts when you walk uphill, if you feel persistently dizzy, if you have collapsed for no obvious reason, if you feel your heart racing or skipping a beat, you should consider visiting a cardiologist for review.
