Disorders of the heart and the arteries (cardiovascular) are very common in our modern world. In fact, every year, more people die from cardiovascular causes than any other disease. The heart can be affected by common health problems, such as hypertension and increased cholesterol, by bad habits, such as smoking and drinking, and by the new “epidemics” of obesity, diabetes and physical inactivity. It is important to know that most cardiovascular diseases can be prevented, if the risk factors that led to them in the first place are promptly treated.

Don’t underestimate your 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.

Dr Karagiannis is an experienced general and acute cardiologist with a special interest in all forms of heart dysfunction (heart failure) and in echocardiography, who can provide you with expert advice about your heart problems. He can offer personalized treatment plans 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). 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.

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 cardiac tests (ECG, Echocardiogram) at the same time. This will save you repeat journey to the clinic.

What patients say

I would like to thank Dr Karagiannis for the care he provided to my father, who suffered from heart failure. He was very keen to explain in simple terms all the aspects of the management of my father’s chronic condition. He was always there for us. We felt supported throughout the way.


I was involved in my care from the beginning to the end. I felt that my concerns and my preferences were addressed and respected.
