30 Facts About Your Heart

Published

on

As you go through your day, you probably don’t spend much time thinking about your heart and all that it’s doing. But let’s take a few moments to appreciate this life-sustaining organ in your chest.

Your heart starts beating well before you’re born and continues its rhythmic work until the day you die. That’s just the start (and end) of its amazing story, though.

Here are a few more heart-related facts, courtesy of cardiologist Brian Griffin, MD.

  1. Your heart beats about 100,000 times per day. During the average person’s lifetime, their heart beats more than 2.6 billion times. (Your pulse is a way you can feel your heart beating.)
  2. The beating sound from your heart — lub-dub, lub-dub, lub-dub — is from the clap of valve leaflets opening and closing.
  3. A typical human heart valve is about the size of a half dollar.
  4. Each minute, your heart pumps nearly 1.5 gallons (5.7 liters) of blood. That’s a pump flow rate that could fill an Olympic-sized swimming pool in less than a year. (Talk about a gold medal effort!)
  5. Your adult-sized heart is about the size of two hands clasped together. A child’s heart is about the size of a single fist.
  6. Location is everything in life, right? That’s true for your heart, too. It’s located in the front of your chest, slightly behind and to the left of your breastbone. Your ribs offer extra protection for the vital organ.
  7. To make room for your heart, your left lung is slightly smaller than your right lung.
  8. Your heart weighs somewhere between 7 ounces and 15 ounces (200 grams to 425 grams), or less than a pound. The average male’s heart weighs 2 ounces (57 grams) more than the average female’s heart.
  9. For comparison’s sake, a blue whale — the world’s largest animal — has a heart weighing more than 1,000 pounds. A person could easily crawl through the aorta in that sized heart.
  10. The smallest animal heart can be found in fairyflies. You’d need a microscope to see the ticker in this tiny insect.
  11. Your heart works as a coordinated machine. The right side of your heart pumps “used” blood from your body into your lungs, where it refills with oxygen. The left side of your heart then pumps re-oxygenated blood back into your body.
  12. Almost every cell in your body gets blood from your heart. The outliers can be found in the corneas of your eyes.
  13. Your heart pumps blood through about 60,000 miles (96,000 kilometers) of blood vessels. To put that in perspective, this blood tubing system could circle the Earth at the equator TWICE.
  14. A female’s average heartbeat is faster than a male’s by almost eight beats a minute. The reason? Because their hearts are usually smaller in size, females need their hearts to beat more to pump the same amount of blood.
  15. A typical heart pumps approximately 4 tablespoons of blood with each beat.
  16. Your heart has its own electrical supply and will continue to beat even when separated from your body. This specialized network of cells is known as the heart’s electrical conduction system.
  17. Heart disease is the greatest single threat to your health and the leading cause of death globally. The good news? You can help manage your heart health through dietary choicesregular exercise and stress management.
  18. It’s true that some heart problems can be inherited. It’s also true that you can minimize their impact by managing blood pressure and cholesterol through a heart-healthy lifestyle. (See #15.)
  19. Runners have a 45% lower risk of heart disease or stroke.
  20. Cardiac health is an age-old issue, as evidence of heart disease has been found in 3,000-year-old mummies.
  21. Research shows that Monday — the start of the traditional work week — is the most common day of the week to experience a heart attack. It’s a phenomenon known as the “Blue Monday” effect.
  22. The holiday season is also heart attack season. More cardiac deaths occur on December 25 than any other day of the year. The second and third-deadliest days are December 26 and January 1.
  23. A joke a day may help keep the heart doctor away, as laughing can improve heart health by lowering stress and relaxing blood vessels. Happiness can lower your risk of heart disease, too.
  24. Why does the heart symbolize love? Probably because of the pitter-patter you feel in your chest when Cupid’s arrow strikes. (But in truth, your brain controls love — but that would make for a lousy Valentine’s Day symbol.)
  25. Despite your heart not being part of making a love connection, it can still be broken when relationships take a bad turn. An emotionally driven condition known as “broken heart syndrome” can temporarily weaken your heart muscle.
  26. Heart cancer is very rare because heart cells stop dividing in adulthood, making them more resistant to the sort of mutations that can lead to cancer.
  27. Modesty prompted the invention of the stethoscope, that iconic medical tool that healthcare providers use to listen to your heart. Before it existed, doctors had to press an ear directly to the chest of their patient.
  28. The world’s first “stopped-heart” surgery took place at Cleveland Clinic in 1956. Today, this type of surgery — which uses a machine to pump blood throughout the body while the heart is stopped during an operation — is commonplace.
  29. A cardiac surgeon at Cleveland Clinic pioneered coronary artery bypass surgery in the late 1960s. The surgery restores blood flow to areas of the heart using blood vessels transplanted from other parts of the body.

Each year, more than 2 million people around the world have open-heart surgery to address various heart conditions.

5.4 Million in Haiti are going hungry as Gangs recruit children, UN calls for Immediate Action

Haiti, December 9, 2024 – The United Nations Economic and Social Council (ECOSOC) is warning that as Haiti grapples with escalating violence and systemic collapse, its children are bearing the brunt of a multipronged crisis that threatens their lives, safety, and future.

UN officials and humanitarian leaders used the ECOSOC meeting last Monday December 2 to highlight the direct conditions in Haiti, where violence has severely disrupted life in the  Caribbean Community (CARICOM) country.

They have called for immediate action to support its youngest citizens.

The UN said 5.4 million people, half the population are facing acute food insecurity and 700,000 displaced, urgent international intervention is needed to address a crisis compounded by armed groups violence, economic instability, and insufficient humanitarian funding.

UN Emergency Relief Coordinator, Tom Fletcher, who took up his post two weeks ago, spoke of the devastating impact of the crisis on children. “The children of Haiti are displaced. They are malnourished. They live in fear, their neighbourhoods controlled by armed groups.”

The Executive Director of the UN Children’s Fund (UNICEF), Catherine Russell said “we estimate that children account for 30 to 54 per cent of armed group members while the total number of children recruited by armed groups has jumped by 70 per cent over the past year.”

She also highlighted the collapse of essential services, with 1.5 million youngsters losing access to education and healthcare facilities shutting down due to violence and insecurity.

Despite the challenges, UN agencies and partners continue to deliver aid.  Facing a surge in displacement and food insecurity, the UN’s World Food Programme (WFP) has announced an expanded response, targeting nearly two million people with emergency relief.

“We have been delivering record amounts of food assistance to Haitians in Port-au-Prince and across the country these past few months and will do even more in the coming weeks,” said the WFP’s Country Director, Wanja Kaaria.

The WFP also supports local economies by sourcing 70 per cent of school meal ingredients from Haitian farmers, fostering long-term resilience and development.

Yet, the scale of the response is dwarfed by the growing needs as speakers at the ECOSOC session stressed the need for immediate international action to close funding gaps, protect children from exploitation, and rebuild essential services.

UN Special Representative Maria Isabel Salvador, who also heads the UN Integrated Office in Haiti (BINUH), urged the global community to address root causes of the crisis.

“The challenges Haiti faces are immense, but one truth is undeniable: no progress can be made without addressing the pervasive insecurity caused by armed gangs.  UNICEF and other humanitarian leaders called on the UN Security Council -backed Multinational Security Support (MSS) mission and Haitian authorities to prioritise child protection during operations, ensuring safe reintegration for children recruited by armed groups.

CARPHA Supports Mass Gathering Surveillance for Bahamas’ National Festivals

Published

on

 

Nassau, Bahamas:  The Caribbean Public Health Agency (CARPHA), in collaboration with The Bahamas Ministry of Health and Wellness, conducted a mass gathering (MG) risk assessment and implemented the MG event-based surveillance for the country’s upcoming annual Junkanoo Festival[1], and other upcoming mass gathering events.

Mass gatherings can pose increased public health risks and challenges for the host community.  In light of this, CARPHA conducted a training workshop to strengthen The Bahamas’ capacity to identify and respond to potential threats, in “real time”, during the festival.  The MG surveillance training was carried out using the novel, electronic, real time, MG surveillance module, developed by CARPHA and successfully utilised in Caribbean nations, during the recently concluded International Cricket Council (ICC) T20 World Cup.

During the launch of the workshop, The Honourable Dr Michael Darville, Minister of Health and Wellness reaffirmed his Ministry’s commitment to implementing proactive surveillance to reduce the risk of disease spread within the population, as well as the significant number of visitors on the islands. Minister Darville acknowledged the “complexities of 12 million visitors coming into a population of 450 thousand” annually and the need to ensure robust and resilient public health systems for the continued economic growth of the country. The Minister also endorsed CARPHA as a key public health partner, saying that the Agency is “a world recognised institution with high-level professionals and leads in many public health programmes especially in tourism”.

Dr Lisa Indar, Ad Interim Executive Director, in her remarks explained the need for elevated surveillance and indicated, “Mass gathering events such as junkanoo, carnival and cricket in the Caribbean are unique and key cultural and economic pillars for all CARPHA Member States (CMS) that draw large numbers of visitors from around the world”.  She added, “visitors no longer just want to be happy, they want to be happy and healthy”.

Dr Indar also spoke about the relevance and benefits of mass gathering surveillance to the overall public health landscape and underpinned the need to ramp-up and utilise the available electronic surveillance tools that will facilitate rapid identification and response to public health threats emerging from mass gathering events.

The CARPHA team presented  Minister Darville with three tablets to facilitate real-time field data entry during the Junkanoo Festival and other mass gathering events throughout the year.  The capacity built from the Junkanoo risk assessment and MG training will be used by The Bahamas’ national planning and coordination team to guide them in developing and implementing relevant risk mitigation strategies and interventions to reduce the festival’s current risks.

This mission was supported through CARPHA’s Pandemic Fund project, which has the core objective of supporting the reduction of public health impact of pandemics in the Caribbean of which mass gatherings pose an ever-present risk.

The launch of the training workshop took place on Thursday 21st November 2024 in The Bahamas.  Attendees included The Honourable Dr Michael Darville, Minister of Health and Wellness, Dr Phillip Swann, Acting Director of the Department of Public Health, Mrs. Coral Miller, Deputy Permanent Secretary Ministry of Health and Wellness, Ms. Brenda Colebrooke, Senior Under Secretary Ministry of Health and Wellness and Dr Felicia Greenslade, Officer-in-Charge of the Surveillance Unit. The CARPHA team comprised Dr Lisa Indar, Ad Interim Executive Director, Mr. Keston Daniel, Coordinator, Visitor-based Surveillance and Mr. Mohamed Elsherbiny, Senior Technical Advisor.

About the Pandemic Fund Project:

The Caribbean Public Health Agency (CARPHA), the sole public health agency for the Caribbean region, is the Executing Agency for the Pandemic Fund (PF) Project: RG-T4387, with the Inter-American Development Bank (IDB) as the Implementing Entity. The goal of this Project, which spans from 2024 to 2026, is to reduce the public health impact of pandemics in the Caribbean through prevention, preparedness, and response (PPR).  The objective is to support the reduction of the public health impact of pandemics in the Caribbean by building pandemic PPR surveillance and early warning systems, laboratory systems and workforce capacity, regionally at CARPHA and at country levels. This will reduce the transboundary spread of infectious diseases and improve regional and global health security. CARPHA is the beneficiary of the PF project and CARPHA Member States are the participants.

The PF was approved at the highest level by the Council for Human and Social Development, as well as by CARPHA’s Executive Board and other stakeholders, including Chief Medical Officers. This is a regional 3-year project (2024-2026). The public signing of Technical Cooperation Agreement to implement the project was on December 14, 2023.

 About the CARPHA Electronic Mass Gathering (MG) Surveillance Module:

The MG surveillance module is a product of the CARPHA’s Tourism and Health Program (THP), one of the Agency’s innovative programmes that addresses health, food safety and environmental sanitation (HSE) threats impacting sustainable tourism in the Caribbean through real-time, early warning and response surveillance systems, guidelines, capacity building, HSE standards, policy, advocacy and partnerships.

In 2024, this portfolio was expanded to included mass gathering surveillance given the elevated public health risk these events pose to regional health security. The THP aims to strengthen countries’ capacity to prepare for and respond to public health threats, thereby improving citizen and visitor health, tourism resilience, economic sustainability and the event itself.

With the success of MG surveillance during the ICC T20 World Cup and the endorsement of this electronic system by Ministers of Health in the Region, through the Council of Human and Social Development-Health, The Bahamas recognised the system’s high value and solicited the support of CARPHA to implement and build capacity in MG surveillance for its annual Junkanoo Festival.

CARPHA Hosts Regional IATA Infectious Substances Transport “Train-the-Trainer” Workshop with the Pandemic Fund’s Support

Published

on

Port of Spain, Trinidad and Tobago – The Caribbean Public Health Agency (CARPHA) concluded its Train-the-Trainer Workshop on the Safe Transportation of Infectious Substances today. The workshop, conducted by the International Air Transport Association (IATA), was supported by the Pandemic Fund grant, with CARPHA serving as the Executing Agency and the Inter-American Development Bank (IDB) as the Implementing Entity.

Fourteen (14) CARPHA Member States (CMS) participated in this initiative, which aimed to strengthen regional capacity to meet international safety standards for shipping infectious substances. The training provided participants with essential theoretical knowledge, interactive discussions, and practical exercises to achieve IATA certification as trainers. These certified trainers will now be well-positioned to serve as national trainers and advisors in biosafety and safe transport protocols, ensuring safer practices across the region.

Dr. Lisa Indar, Ad. Interim Executive Director of CARPHA, highlighted the significance of the initiative: “As a region, we must ensure that the transportation of infectious substances meets international safety standards to protect our public health systems and communities. This workshop builds on CARPHA’s commitment to developing a robust network of certified trainers who can implement and sustain best practices in their home countries. We are grateful for the training supported by the Pandemic Fund project, enabling us to take key steps in pandemic preparedness and response.”

The program not only addressed gaps in Certified Infectious Substance Transport Training within CMS, but also established mechanisms for monitoring and evaluating the trainers’ impact in their respective countries. Participants are expected to conduct infectious substances transport training within the first quarter of 2025, ensuring the rapid application of their certification.

Speaking at the opening ceremony, Dr. Horace Cox, Acting Director of Surveillance, Disease Prevention and Control at CARPHA, remarked: “The effectiveness of our public health response hinges on having a cadre of professionals who can translate this critical knowledge into action at the country level. This program empowers Member States to strengthen their capacity to handle infectious substances safely and securely, which is a cornerstone in bolstering regional health systems and pandemic preparedness and response.”

To ensure the sustainability of the training program, CARPHA is also establishing mechanisms for ongoing feedback and continuous improvement, ensuring that the program remains dynamic and responsive to the needs of the Member States and trainees. These efforts promise to enable better tracking of training activities and contribute to the long-term sustainability of the training program. This initiative is part of CARPHA’s broader mission to enhance laboratory capabilities, improve surveillance systems, and ensure public health security across the Caribbean. By creating a robust network of self-sufficient trainers in its Member States, CARPHA aims to strengthen the capacity for safely shipping infectious substances and enhance regional public health resilience.
