Welcome to my podcast. I am Doctor Warrick Bishop, and I want to help you to live as well as possible for as long as possible. I’m a practising cardiologist, best-selling author, keynote speaker, and the creator of The Healthy Heart Network. I have over 20 years as a specialist cardiologist and a private practice of over 10,000 patients.

The episode discusses common cardiac drugs and some potential drug interactions. It covers aspirin, warfarin, clopidogrel, proton pump inhibitors, beta blockers, ACE inhibitors, digoxin, nitrates, and amiodarone. Notably, grapefruit can increase serum levels of beta blockers, calcium channel blockers, and some statins, potentially leading to toxicity.


  • Aspirin is commonly used to thin the blood and prevent clotting by blocking platelets. It can interact badly with other blood thinners like clopidogrel.
  • Warfarin works by interfering with vitamin K and the coagulation cascade. It can be affected by foods high in vitamin K like leafy greens. Consistency is important.
  • Clopidogrel blocks platelets and works with aspirin, but proton pump inhibitors like omeprazole can reduce its effectiveness.
  • Beta blockers can have their levels increased by grapefruit juice through metabolic interactions.
  • Grapefruit can also increase calcium channel blockers and some statins through similar mechanisms.
  • ACE inhibitors and diuretics like furosemide can interact around potassium - monitoring is important.
  • Digoxin toxicity is a risk with low potassium.
  • Sublingual nitroglycerin and Viagra-like drugs can dangerously lower blood pressure together.
  • Amiodarone absorption is increased by high fat meals due to its fat solubility.
  • The podcast provides information on common cardiac drugs and warns of important drug-drug interactions.

Warfarin's effects can be altered by foods high in vitamin K like leafy greens. Clopidogrel's effectiveness may be reduced when taken with proton pump inhibitors like omeprazole. Combining nitrates with phosphodiesterase inhibitors like sildenafil can cause profound blood pressure drops. The host recommends being aware of possible drug interactions and maintaining regular communication with doctors.

Australia, like the rest of the western world, has a heart problem.

Over 9 million people around the world die from heart disease every year.

Every 10 minutes, someone in Australia suffers a heart attack. And 21 lives are lost daily because of it.

The devastating fact in all of this is… 

Almost every one of those cases could have been prevented. 

This podcast is for anyone who wants to improve their health literacy and gain information to help them make the best decisions about their risk of heart attack, their cholesterol, blood pressure, risk of diabetes, weight loss and general health. Join me on my personal mission journey to prevent Heart Attack on a global scale. If you like this podcast, I would be honoured by a 5-star review and appreciate if you let your friends and family know about this podcast; you may even save the life of someone you love!

Are You at Risk of a Sudden Heart Attack? How Healthy is Your Heart? Really?

Heart disease is the #1 killer in the Western World. In Australia, someone dies every 28 minutes from heart disease. That’s 51 people a day. In the US, someone has a heart attack every 40 SECONDS! Fortunately, many heart attacks are preventable. However, regular exercise and eating healthy are no guarantee you won’t succumb to this silent killer.

  • 94% of Australians have at least One Risk Factor for heart disease.
  •  59% of Australians have been Touched by heart disease.
  •  Yet only 3% of Australians have had a Full Heart-Health Assessment in the past 12 months.
