I was born in Dublin, but we moved to Wexford when I was very small, and I grew up and went to school there.<\/p>\n

My parents weren\u2019t intentionally health-conscious, but they always led a very healthy lifestyle. My mum really believed in whole foods and cooking from scratch, so I was raised on fresh ingredients and home-cooked food.<\/p>\n

I grew up on a farm, and there was a huge expectation that we played outside, looked after the horses, and helped out.<\/p>\n

I first trained to be a radiographer and worked as one for about nine months. While doing that, I got to work in the cath [cardiac catheterisation] lab, and from then, I knew I wanted to go to medical school.<\/p>\n

Like many people, I wasn\u2019t as health-conscious in my late teens, and when I went to college, but going back to college and studying medicine, and realising in my working life that you can\u2019t burn the candle at both ends, definitely brought me back around to living a much healthier lifestyle.<\/p>\n

I went back to medical school in UCC, and did the graduate programme, then moved to the US for my postgraduate training. Once I\u2019d started my postgrad training in internal medicine, I knew I wanted to be a cardiologist. I loved that you get to see patients in clinic and follow them longitudinally. You can do procedures, read diagnostic studies, and take care of critically ill patients.<\/p>\n

I considered whether I\u2019d stay in the US, but I\u2019m married with two young kids, so we decided we wanted to come home to Ireland and be closer to family. We moved back last May.<\/p>\n

Being a cardiologist and knowing more about the risks of not following a healthy lifestyle has certainly made me much more conscious [of my choices] in recent years. As more information and data come out, it continues to influence me to be healthier.<\/p>\n

The things we most commonly see in clinic are people presenting for management of high blood pressure and high cholesterol. We also frequently see patients who are being referred because they have a strong family history of heart disease. In terms of metabolic conditions, we often see patients who have obesity or type 1 or type 2 diabetes, which tend to feed into their overall risk profile for developing heart disease.<\/p>\n

Patients often think it is older men who tend to be affected [by heart disease], when the reality is that men and women are at equal risk of developing it. And we often see heart disease developing in younger patients, in particular those who have underlying risk factors [such as] metabolic conditions, high blood pressure, high cholesterol, or a strong family history.<\/p>\n

Another major myth is that a lot of people think heart disease is related [only] to genetics. Genetics plays a part, whereas lifestyle factors play another large role. I think this sometimes surprises patients.<\/p>\n

My top tips for maintaining a healthy heart as we age:<\/p>\n

\n 1. High blood pressure: It is one of the biggest risk factors for heart disease and tends not to cause symptoms. High blood pressure is very easy to pick up using home blood-pressure monitoring, or by getting in-office or 24-hour blood-pressure monitoring organised by your GP.<\/p>\n

There are some nuances to these [numbers], but if you\u2019re monitoring your blood pressure at home, numbers that are consistently greater than 140 over 90 warrant further workup, typically with a 24-hour blood pressure monitor.<\/p>\n

Lifestyle absolutely matters when it comes to blood pressure. One of the key things people can do is follow a low-salt diet. Wherever salt goes, water follows, and that raises blood pressure, so reducing salt is always recommended.<\/p>\n

Weight loss, where indicated and possible, can also have a dramatic impact on blood pressure and, in some cases, medications can be reduced.<\/p>\n

Exercise is also super important and has a real impact on lowering blood pressure.<\/p>\n

\n 2. High cholesterol: A second major risk factor for heart disease \u2014 again, in the vast majority of patients, it will not have any external indicators, but it\u2019s very easy to pick up on routine blood testing.<\/p>\n

In general, a total cholesterol greater than five or an LDL greater than three would be considered high. That doesn\u2019t mean that you need to be on medication, but it warrants further discussion with your GP or cardiologist.<\/p>\n

Studies show that the Mediterranean diet helps reduce blood pressure, it improves your cholesterol profile, and it lowers inflammation. It\u2019s a great place for people to start.<\/p>\n

There are patients who will never get their high blood pressure or cholesterol under control just using diet and exercise. They need medication. We always recommend lifestyle modifications, but in conjunction with medications where indicated.<\/p>\n

\n 3. Manage your lifestyle: It\u2019s one of the most important factors in prevention and long-term outcomes. Many of the largest risk factors for developing cardiovascular disease \u2014 like high blood pressure, high cholesterol, type 2 diabetes, obesity, and smoking \u2014 are strongly influenced by your daily habits.<\/p>\n

Regular physical activity, a balanced diet, good sleep, stress management, maintaining a healthy weight, avoiding or limiting alcohol, and avoiding smoking; all of these will, over your lifetime, reduce your risk of heart disease, of stroke, of other vascular diseases.<\/p>\n

If you can do a brisk walk outside for 30 minutes, three to five days a week, and you do that consistently, that\u2019s going to have a dramatic positive impact on your cardiovascular health over time.<\/p>\n

\n 4. Eat a Mediterranean diet: This diet is probably one of the most well-studied dietary patterns when we look at cardiovascular research, and there is evidence that consistently links it with improved heart health and lower cardiovascular risk. It emphasises fruits, vegetables, whole grains, legumes, nuts, olive oil, fish, and a moderate intake of dairy.<\/p>\n

There\u2019s growing evidence that ultra-processed foods are detrimental to our health, so where possible, I recommend limiting them and cooking whole foods at home as much as you can.<\/p>\n

\n 5. Get a good night\u2019s sleep: The evidence is evolving to show that sleep is really important. Poor sleep [has] been associated with higher risks of high blood pressure, obesity, type 2 diabetes, heart disease, stroke and heart rhythm issues. Good-quality, consistent sleep should be viewed as one of the core pillars of preventative health, alongside diet, exercise, smoking cessation, and the other lifestyle modifiers.<\/p>\n

Look at things that are easy to fix, such as not using your phone or looking at screens before bed, avoiding caffeine later in the day, and limiting alcohol intake.<\/p>\n

Exercise has been linked to an improvement in sleep health.<\/p>\n

If I have a patient who has poor sleep and has another risk factor for sleep apnoea, such as an elevated BMI or hypertension, I\u2019ll send that person for a sleep study.<\/p>\n

\n 6. Women\u2019s symptoms can be different to men\u2019s: Women present differently to men in terms of symptoms of heart attack [and] underlying heart disease.<\/p>\n

Women tend to describe symptoms like fatigue, decreasing exercise tolerance, or shortness of breath, whereas men will often describe chest pain.<\/p>\n

\n 7. Consider screening, if appropriate: Patients with a strong family history of early heart disease \u2014 parents or siblings who\u2019ve had heart disease \u2014 should think about getting themselves screened and whether they have underlying risk factors that might further increase their chances of developing heart disease.<\/p>\n

And for women in particular, if they\u2019ve had complications in pregnancy \u2014 high blood pressure in pregnancy, pre-eclampsia, eclampsia, gestational diabetes, or preterm labour [before 37 weeks] \u2014 we know those patients are at an increased risk over time of developing underlying heart disease. Those patients warrant getting themselves checked out.<\/p>\n

Top tip: If I could tell patients one thing, it would be: do not smoke cigarettes. And if you do, quit. That\u2019s probably the best thing you can do for your heart health and overall health.<\/p>\n","protected":false},"excerpt":{"rendered":"I was born in Dublin, but we moved to Wexford when I was very small, and I grew…\n","protected":false},"author":2,"featured_media":509592,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[33970,103,61,60],"class_list":["post-509591","post","type-post","status-publish","format-standard","has-post-thumbnail","category-health","tag-health-body","tag-health","tag-ie","tag-ireland"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/509591","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=509591"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/509591\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/509592"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=509591"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=509591"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=509591"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
