Dietary changes and weight management:

Eat a low-sodium diet. Limit sodium intake to less than 2,000 mg per day. Read food labels carefully and avoid adding salt when cooking or at the table. Some high sodium foods to avoid include canned soups or veggies, frozen meals, lunch meats, salad dressings, and condiments.
Follow a heart-healthy diet high in fruits and vegetables, whole grains, and lean sources of protein. Bake, broil, or grill meats instead of frying. Choose skinless poultry and fish more often.
Achieve and maintain a healthy weight. Losing extra pounds takes pressure off your heart. Work with your doctor and dietitian to determine your ideal body weight based on factors like your height, age, gender.
Limit added sugars and refined carbohydrates, which can cause blood sugar and insulin spikes. Opt for whole, minimally processed carbohydrates like brown rice, oats, quinoa, beans, lentils, potatoes instead.
Drink plenty of water to stay hydrated and allow your heart to function more efficiently. Aim for a minimum of 8 glasses per day.


Engage in regular aerobic exercise on most days of the week according to your abilities. Activities like walking, using a stationary bike, swimming, and water aerobics are great options.
Start slowly if you have not exercised before. Consult your doctor on the appropriate intensity and duration based on your functional capacity. Slowly increase your activity levels over time under medical guidance.
Aim for at least 30 minutes of moderate exercise on most or all days. It’s okay to break it up into smaller 10 minute chunks if needed.
Incorporate strength training exercises using free weights, resistance bands, or your own body weight twice a week. This helps build muscle and increase metabolism.

Stress management:

Use relaxation techniques like deep breathing, mindfulness meditation, yoga, tai chi to help cope with stress. Make it part of your daily self-care routine.
Prioritize sleep and aim for 7-8 hours every night. Poor sleep overworks the cardiovascular system.
Spend time doing activities you enjoy every day like a hobby, reading, spending time with loved ones. Good social connections and a positive approach to life helps lower stress.

Reduce alcohol intake:

Limit alcoholic drinks to no more than 1-2 per day for men, and 1 drink per day for women. Too much alcohol is hard on the heart and liver.
Avoid binge drinking completely since it causes irregular heartbeats and increases heart failure risks.

Smoking cessation:

If you smoke, quit. Smoking significantly increases heart disease risks. Consult your doctor about available smoking cessation programs and strategies. Use nicotine replacement treatment if needed.
Avoid secondhand smoke too. Don’t let others smoke around you.

Take medications as prescribed:

Heart failure symptoms often worsen if medications are missed or not taken correctly. Use a pill dispenser or daily checklist to stay on track. Time dosage with meals if instructed.
Carry your medications with you outside the house so you don’t forget a dose if away from home. Ask your pharmacist any questions you have.
See your doctor as scheduled for medication adjustments, refills, and to monitor your condition over time. Medication changes are common to ensure the most effective management.


Weigh yourself daily and record your weight on a calendar or tracker to spot sudden weight gain from fluid retention early. Report increases of 3 pounds or more in a day to your doctor.
Check your ankles, legs and abdomen for swelling and call your healthcare team if you notice it. Swelling could mean your fluid levels need adjusting.
Track your symptoms, exercise durations, diet and other lifestyle factors in a journal. This helps you identify patterns and report changes accurately to your clinician.

Lifestyle changes take commitment but can go a long way in managing heart failure and preventing complications over the long run when combined with medical therapy. Remember to start slowly, celebrate even small successes, and speak to your doctor anytime you have difficulty adhering to recommendations. A heart-healthy lifestyle is vital for ongoing heart health.


A failure modes and effects analysis (FMEA) is a systematic process for evaluating potential failure modes within a system or design and assessing the relative impact of those failures. By conducting a thorough FMEA, engineers can gain valuable insights into ways the system may fail and assess how to minimize risk and the effects of any potential failures that do occur. Some key findings that could emerge from a comprehensive FMEA may include:

The FMEA would carefully examine each component, subsystem and interface within the overall system or design. Engineers would evaluate potential ways that each part could fail to perform its intended function, considering factors such as material defects, wear and tear, excessive stresses, improper assembly, incorrect operational parameters, etc. Through this process, certain components may be identified as having higher failure potential due to their complexity, number of failure modes, operating stresses or other risk factors. For example, some parts that interface with users or are exposed to harsh environmental conditions could emerge as particular risk areas based on potential failure modes.

Upon determining all potential failure modes, the team would then assess the impact or severity of each failure on system performance, safety and other critical attributes. Some failure modes, even if relatively unlikely, may carry catastrophic or critical consequences like injury, system damage or inability to complete a primary function. Other failures may only cause minor quality issues or inconveniences. This severity analysis helps identify where design or process changes could help minimize overall risk. Certain component failures or failure combinations ranked with high severity may warrant immediate design focus or additional controls.

An important consideration would be the likelihood or probability of each specific failure mode occurring. Factors like history of similar parts, design maturity, manufacturing processes and component stresses are evaluated. Failures seen as very likely due to high risks require special attention versus others seen as only remotely possible. Combining severity and occurrence evaluations into an overall risk priority number, the FMEA can objectively pinpoint the highest priority issues to address proactively through design or process improvements.

Patterns may emerge implicating certain suppliers, manufacturing steps, environmental conditions or other root causes as contributing factors in multiple failure modes. For example, if many failures can be traced to variations in a critical material property, material certification and testing processes may need review. Such systematic insights help prioritize the most valuable corrective and preventive actions to take.

Recommended actions are formulated to reduce occurrence and/or minimize impact of the highest risk failures. These may include design changes like adding features to reinforce weaknesses, improve inspection points, or adding redundancies. Process recommendations could involve tightening controls, adding process validation checks, supplying staff training and so on. An effective FMEA drives continuous improvement by prioritizing actions supported by objective analysis.

Once improvements are made, the FMEA should be recalculated or revisited periodically over the system’s life cycle to verify effectiveness and consider additional learning from field data. New potential failure modes may emerge as designs or usage profiles evolve too. Periodic review ensures the analysis stays aligned with current conditions.

A robust FMEA process involves cross-functional perspectives in the analysis and uses its findings to help develop comprehensive reliability test plans as well as maintenance and inspection protocols. The end goal is achieving an optimal balance of high reliability, safety and cost-effectiveness throughout the system’s lifecycle. When consistently applied and maintained, FMEA can significantly reduce development and operational risks.

A thorough failure modes and effects analysis provides a rigorous, evidence-based process for identifying and prioritizing reliability and safety concerns within a system or design. Its key findings light the path for targeted improvements to minimize overall risks and their impacts on performance, schedule and budgets. Used effectively, FMEA drives powerful gains that resonate throughout the development, production and field support phases of any product or operation.
