I recently saw Dr. Francesco Lo Monaco after experiencing chest pain and worrying it could be heart-related. He was attentive, thorough and highly efficient, quickly reassuring me through the appropriate tests that my heart was healthy and the pain was not cardiac-related. I would highly recommend him. A special mention also goes to Alessandra, his assistant, who is an absolute gem. She was incredibly efficient, responsive and kept me informed throughout the entire process. An excellent team and a very reassuring experience from start to finish.

I went to see Dr Lo Monaco after having an unsatisfactory appointment with a different cardiologist, I cannot recommend Dr Lo Monaco enough, his attention to detail was unparalleled and he took the time to go into my history and ensure that he had every detail of my health covered, he was very very pleasant, calm, reassuring and made sure I had a comprehensive and detailed picture of my heart health, I cannot stress enough that no matter how unsure you are about your heart health, this is definitely the place to go, it was comforting to know that any worries I had, no matter how slight or great, they were all met with the same high level of attention, I feel so much more relaxed about my heart health after my appointments with Dr Lo Monaco, he is an absolute gentleman and a shining example of what the medical profession should be

I cannot recommend Dr. Francesco Lo Monaco highly enough. From my initial consultation regarding concerning chest pain, his level of care, professionalism, and expertise were truly outstanding. What immediately sets Dr. Lo Monaco apart is his incredible attention to detail and active listening. During our meeting, he asked all the right questions and took note of every single detail of my medical history and symptoms without missing a single thing. He made me feel completely heard and valued as a patient. When it came to investigating my chest pain, his approach was methodical, targeted, and refreshingly ethical. Rather than ordering a blanket of unnecessary procedures that would only drive up costs, he carefully selected the exact diagnostics needed for an accurate diagnosis. His care was seamless across both The Clementine Churchill Hospital and The National Heart Clinic on Harley Street, where I underwent an ECG, an angiogram, a 72-hour heart monitor, and stress tests. Throughout the testing process, Dr. Lo Monaco explained every procedure clearly, ensuring I felt completely at ease. He is deeply personal, deeply caring, and represents the absolute gold standard of what a consultant cardiologist should be: brilliant clinically, transparent with costs, and wholly dedicated to his patients' well-being. If you are looking for a top-tier heart specialist in London, look no further.

The most positive experience with Dr Francesco Lo Monaco and team. Punctual and flexible call hours, extremely astute and efficient learn health history, cover/test a very wide range of variables related, and confident/ making me confident in the diagnosis. All of which was accomplished within a short period (some of which was done remotely as well). Equally, Dr Francesco Lo Monaco‘s team of doctors and nurses were professional, knew exactly what they were doing and polite/welcoming the whole time. My most “heart” felt thank you to the Doc and team, and can only offer my highest recommendations!

Dr Lo Monaco is very patient focused and clearly explains the results of tests and what he recommends as the next steps. His calm demeanour and clear explanations are very reassuring. He also has a very efficient and friendly support team.

I simply cannot put into words how grateful I am for Dr Lo Monaco. When I was worried and unsure about my heart health and DCB procedure, he didn’t just treat my condition he truly cared for me. He listens with such kindness, explains everything until I understood, and gave me the courage and reassurance I so desperately needed. His skill, patience and gentle nature have made such a huge difference to my recovery and my life. He is not just an outstanding doctor, but a truly wonderful human being. I feel blessed to be under his care , thank you from the bottom of my heart.

Dr. LoMonaco is an exceptionally caring, attentive, and knowledgeable cardiologist. From my very first appointment, I felt truly listened to and cared for. He takes the time to explain medical terms and treatment options clearly and patiently, which makes a real difference. His team is equally kind, responsive, and attentive to every detail. I feel incredibly fortunate to have found Dr. LoMonaco and would wholeheartedly recommend him to anyone looking for a cardiologist who combines outstanding expertise with genuine compassion.

WHAT IS CARDIAC SYNCOPE?

Cardiac syncope is a temporary loss of consciousness caused by an interruption in blood flow to the brain, often due to an underlying heart rhythm abnormality or cardiovascular issue. Although symptoms may appear similar, cardiac syncope is different from vasovagal syncope (common faint), which is typically triggered by a drop in blood pressure, dehydration, emotional stress, or sudden postural changes in people suffering from Postural Orthostatic Tachycardia Syndrome (POTS).

CARDIAC SYNCOPE SYMPTOMS

Syncope does not always show warning signs. However, some individuals may experience symptoms just before a fainting episode, including:

  • Dizziness or lightheadedness
  • Blurred vision
  • Unusual fatigue or Weakness
  • Sweaty Palms
  • Palpitations

Note: If you experience one or more of these symptoms, lie down immediately and raise your legs slightly. This can help improve blood flow to the brain and may reduce the risk of fainting. If symptoms persist or episodes recur, it’s important to visit a private syncope clinic nearby and seek specialist assessment.

WHAT CAUSES CARDIAC SYNCOPE?

Cardiogenic syncope can result from underlying heart rhythm disturbances or structural and functional defects. These issues may reduce blood flow, leading to a sudden drop in oxygen supply to the brain and causing fainting. Common causes include:

  • Genetic conditions affecting heart rhythm, such as Brugada syndrome
  • Aortic dissection, a serious condition caused by a tear in the aorta
  • Aortic valve stenosis, where the aortic valve becomes narrowed
  • QT interval abnormalities, which can lead to dangerous heart rhythm disturbances.

GET AN EXPERT SYNCOPE DIAGNOSIS AT HARLEY STREET CLINIC

Dr Francesco Lo Monaco diagnoses syncope through a comprehensive and structured approach, beginning with a detailed clinical history and physical examination to understand your symptoms and triggers. For detailed insights, he may recommend investigations, such as an ECG, Echocardiogram, Holter Monitoring, Tilt table testing, or even more comprehensive heart tests when required. This thorough approach helps identify the underlying cause, such as reflex syncope, orthostatic hypotension, or cardiac arrhythmias.

TREATMENT & MANAGEMENT OF SYNCOPE

Once the underlying cause is diagnosed, Dr Francesco Lo Monaco develops a personalised management plan tailored to your individual needs. It may include reviewing current medications, optimising lifestyle, or introducing appropriate therapies where required. You will receive clear, expert guidance about medicinal, lifestyle, and, if necessary, procedural options to help you understand your condition, reduce future risk, and manage symptoms effectively.

PREVENTION AND LIFESTYLE MANAGEMENT

Simple lifestyle adjustments can play an important role in reducing the frequency and severity of syncopal episodes. Dr Francesco Lo Monaco provides specialist syncope care and advises maintaining good hydration, recognising and avoiding personal triggers, and making gradual postural changes to help minimise the risk of fainting.
