Content
0.32 -> a few of you have been asking me to make
2.639 -> a video about heart failure
4.96 -> it's actually a topic that is close to
7.04 -> my own heart as i've spent much of the
9.12 -> last decade as a research physician
11.36 -> looking after patients with chronic
13.2 -> heart failure my aim is to give you
15.599 -> a broad overview on how and why heart
18.56 -> failure happens as well as some of the
20.16 -> latest treatments
21.439 -> i'll try to include some of my tips that
23.6 -> i've learned along the way
25.039 -> from both clinicians and sometimes the
27.439 -> patients themselves
30.73 -> [Music]
32.64 -> what is heart failure as i'm sure you
35.36 -> already know the heart is a
37.2 -> pump which pushes and pulls blood around
39.84 -> the body
40.64 -> in heart failure the pump does not work
42.559 -> as well as it should and usually gives
44.719 -> people
45.2 -> significant symptoms this happens
47.44 -> because of a number of causes which i'll
49.36 -> talk about soon
50.96 -> roughly there are two types of heart
53.52 -> failure and this
54.719 -> matters in terms of what treatments can
57.28 -> be used
58.48 -> firstly there is heart failure with
61.039 -> reduced ejection fraction
62.879 -> which tends to affect men who have
65.28 -> underlying coronary artery disease
67.92 -> secondly there is heart failure with
69.76 -> preserved ejection fraction which tends
71.76 -> to affect
72.479 -> older people women and those who are
75.28 -> obese
76.24 -> ejection fraction simply means the
78.799 -> percentage of blood that is
80.64 -> pumped out of the heart with each
82.56 -> heartbeat
83.68 -> if it's less than 50 it has reduced
86.08 -> ejection fraction
87.119 -> and if it is more than 50 it is
89.28 -> preserved ejection fraction heart
90.799 -> failure
91.84 -> what are the symptoms of heart failure
95.2 -> breathlessness or the more technical
97.2 -> term dyspnea
98.56 -> this is most obvious at night time where
100.64 -> you may notice
101.6 -> that you can't lie flat or you have to
104.079 -> sleep in a chair
105.28 -> or suddenly need to sit up to get your
107.2 -> breath the medical term for
109.04 -> breathlessness when lying flat is called
111.52 -> orthopedia also it's really common that
114.079 -> people notice they can't walk as far as
116.24 -> they used to
117.119 -> without feeling very breathless for
119.52 -> example they used to be able to play
121.28 -> a normal round of golf but now they
123.52 -> struggle with the first hole or walking
125.84 -> ten meters
127.119 -> sometimes you'll see the acronym
128.92 -> s-o-b-o-e and medical records
131.36 -> which means shortness of breath on
133.12 -> exertion
134.56 -> fluid classically people notice fluid
137.04 -> around their feet
138.16 -> ankles and legs the medical term is
140.64 -> pitting edema
141.84 -> which means if you push with your finger
144.16 -> it leaves
144.879 -> an indent it tends to build up over the
147.599 -> day
148 -> and is better in the morning for men
150.239 -> it's really typical
151.68 -> to have fluid build up all around the
153.92 -> tummy as well
155.12 -> where you can't get your belt closed and
156.959 -> you can't blame it on eating too much
159.68 -> tiredness heart failure is exhausting
162.879 -> and every activity feels like such an
165.36 -> effort to complete like
166.879 -> having a shower or making the bed it's
169.519 -> common for
170 -> people to lose their appetite with more
171.92 -> severe heart failure as well
174.08 -> what causes heart failure heart failure
177.599 -> can either start
178.64 -> suddenly which is called acute heart
180.879 -> failure
181.76 -> or gradually chronic heart failure
185.36 -> in general there are seven major
187.12 -> culprits that all put stress on the
189.519 -> heart
190.319 -> but i'll list other causes in the
191.84 -> description for you as well
194.319 -> number one high blood pressure if blood
196.8 -> is going through the heart
198 -> under very high pressure the heart
200.319 -> muscle gets bigger to deal with it
202.4 -> but will eventually give up the go if
204.239 -> it's too much
206 -> number two coronary artery disease this
209.04 -> affects the health of the walls of the
211.2 -> heart
212.4 -> number three heart valve diseases narrow
215.44 -> or floppy heart valves put extra stress
218.159 -> on the heart this can be through a
220.159 -> restricted outlet
221.519 -> or incompetence of the valve so blood
224.159 -> leaks backwards
226.08 -> number four medications and drugs this
228.48 -> is a very important cause where
230.239 -> chemicals can damage the heart muscle
232.879 -> especially too much alcohol cocaine
235.68 -> methamphetamines
236.72 -> and unfortunately some types of
238.08 -> chemotherapy agents
239.76 -> are very toxic to the heart number five
243.28 -> chronic arrhythmias
244.799 -> the main one is uncontrolled atrial
246.72 -> fibrillation which causes a disruption
248.879 -> of the heart's usual pacemaking
252.239 -> number six nutritional and hormones
254.879 -> things like anemia
256.16 -> thyroid disease obesity and thymine
258.4 -> deficiency
259.44 -> all put stress on the heart number seven
262.32 -> unknown
263.199 -> sometimes the cause of heart failure is
265.04 -> classified as unknown
266.88 -> when multiple investigations fail to
269.44 -> identify any specific
270.8 -> underlying factors how is heart failure
274.08 -> diagnosed
275.919 -> in my experience people with heart
278.08 -> failure usually present
279.84 -> in two major ways either the patient is
282.8 -> admitted to their local hospital because
284.88 -> they are acutely breathless
286.8 -> and are then tested for heart failure or
289.68 -> they go to their gp because their
291.36 -> symptoms have been getting worse
293.04 -> especially fluid retention tiredness and
295.919 -> breathlessness
297.199 -> a doctor will normally examine your
298.8 -> heart and listen to your lungs
300.72 -> do an ecg to check for heart rhythm
302.88 -> problems and then perform a special
304.88 -> blood test called
306.08 -> bmp or pro bmp this is a hormone that
309.52 -> leaks from your heart muscles when the
311.12 -> cells are stretched
312.479 -> and is very specific to heart failure
314.88 -> this can also be measured over time to
316.96 -> see how well your heart failure is
318.56 -> controlled
319.68 -> the only way to formally diagnose the
321.84 -> type of heart failure
323.199 -> so reduced or preserved ejection
325.12 -> fraction is to have an echo or
327.72 -> echocardiogram
328.96 -> which is an ultrasound of the heart it
331.44 -> is important to have this test because
332.96 -> it will determine
334 -> what type of heart failure you have and
336.479 -> therefore the best treatments going
338.24 -> forward
339.52 -> what are the treatments for chronic
341.36 -> heart failure
343.28 -> right i will try to make this as simple
346.32 -> as possible for you
347.759 -> and remember that this is just an
349.36 -> overview specific advice for individuals
352 -> can be sought from a family doctor
354 -> or cardiology specialists as always the
357.44 -> idea behind
358.479 -> any treatment is to treat the underlying
361.039 -> cause
361.84 -> so if for example your heart failure was
364.16 -> caused by an overactive thyroid
366.56 -> then sorting out the thyroid will
368.08 -> usually settle your heart failure
369.44 -> symptoms
370.4 -> of course your doctor will guide you on
372.319 -> this
373.44 -> there are also some really important
376.72 -> general lifestyle tips that i would
378.56 -> strongly encourage you to
380 -> do which are lose weight if you are
382.8 -> overweight
383.919 -> this reduces the overall strain on your
386.4 -> heart
387.12 -> if you are underweight on the other hand
389.28 -> your doctor may give you
390.56 -> nutritional supplements stop smoking
393.44 -> this will help any underlying heart
395.36 -> disease and help your health in many
397.12 -> other ways too
398.479 -> exercise i know it may sound
400.88 -> counterproductive to put strain on your
402.8 -> heart
403.44 -> but exercise in any small way is really
405.6 -> good for you i'd suggest
407.199 -> regular low intensity exercise avoid
410 -> alcohol
410.96 -> i personally recommend to completely
412.96 -> eliminate alcohol
414.319 -> but at the very least cut it right back
416.88 -> alcohol is associated with arrhythmias
418.8 -> and has direct
419.759 -> toxic effects on our heart muscle
422.8 -> daily weight another very important
425.52 -> activity people with heart failure
427.199 -> should do is to weigh yourself every
429.36 -> morning
430.4 -> this is because you will detect changes
433.039 -> in your fluid levels
434.56 -> by sudden increases in weight for
436.8 -> example if you put on
438.08 -> two kgs or four pounds in a day you have
440.8 -> accumulated fluid
442.16 -> and may need to adjust your medications
445.039 -> number six control blood sugars if you
447.039 -> have diabetes
448.479 -> next i'm going to run through the
450.479 -> medications available
452.16 -> and the evidence behind them for reduced
455.28 -> ejection fraction heart failure which
457.039 -> used to be called systolic heart failure
459.28 -> there are four types of medicines that
461.44 -> are normally given
462.96 -> firstly a diuretic or water tablet such
465.599 -> as frozen mind
466.96 -> this acts on the kidneys to remove
469.599 -> excess fluid
470.72 -> and usually makes people feel much
472.479 -> better in themselves
474.08 -> it won't change the course of heart
476 -> failure but it gives you
477.599 -> some control over your symptoms
480.96 -> secondly ace inhibitors are used which
483.44 -> are a type of blood pressure pill
485.44 -> that acts on the blood vessels and
487.68 -> kidneys
488.72 -> for example enalapril thirdly beta
491.919 -> blockers
492.56 -> are given which reduce the pressure on
495.199 -> the heart
496.08 -> and slow the heartbeat down for example
498.639 -> metoprolol
500.08 -> both beta blockers and ace inhibitors
502.16 -> have the best evidence in prolonging
504.72 -> life expectancy and improving illness
507.199 -> but they have their drawbacks in terms
509.44 -> of side effects
510.639 -> and are not suitable for all cases
513.68 -> then there is spironolactone this is a
516.08 -> type of diuretic which can help the
517.839 -> symptoms of heart failure
519.599 -> again one has to be very careful with
521.279 -> this medication because it can
523.12 -> cause high potassium in the blood and
525.68 -> make people susceptible to falling over
528.08 -> i've talked about this in my video on
530 -> spironolactone
531.92 -> there are newer medications available
534.24 -> such as saccubitural or valsartan
536.72 -> which look promising but it has its own
539.92 -> issues with side effects like dizziness
541.92 -> and
542.32 -> could possibly increase one's risk of
544.16 -> dementia
545.6 -> unfortunately for preserved ejection
547.6 -> fraction heart failure which used to be
549.44 -> called
550.16 -> diastolic heart failure there is limited
552.88 -> evidence for the treatments currently
554.959 -> available
556.08 -> it's really about focusing on all the
559.04 -> lifestyle measures i mentioned
560.88 -> and getting your fluid balance right by
562.959 -> using diuretics like frozomide or
565.2 -> spironolactone
566.64 -> if the symptoms are very bad some
568.32 -> doctors will advise to restrict fluid
570.64 -> intake to between 1.5 to 2 liters a day
574.16 -> additionally your doctor will probably
575.519 -> want to keep a close eye on your blood
577.68 -> pressure
578.16 -> and pulse what is the outlook for heart
580.72 -> failure
582 -> this is a tricky question to answer as
585.2 -> everyone is very different with
587.279 -> different underlying medical conditions
589.6 -> and different causes of heart failure
592.16 -> overall the five year survival rate is
594.08 -> about 50
595.519 -> but for those who have reversible causes
597.36 -> of heart failure they should be able to
599.44 -> completely recover
601.04 -> not surprisingly severe heart failure
603.12 -> will have a worse prognosis
605.12 -> while milder heart failure is compatible
607.68 -> with a longer life expectancy
609.76 -> although the prognosis for heart failure
611.68 -> may be unnerving
613.12 -> there are numerous lifestyle changes and
615.04 -> medications that can help
616.72 -> slow down the progression of the
618 -> condition and increase your chances of
620.16 -> survival
621.2 -> i'd recommend to control the factors you
623.279 -> can change including
624.56 -> monitoring your weight exercising and
627.12 -> eating a healthy diet
629.279 -> please let me know in the comments what
631.36 -> you want to learn more about
633.2 -> thanks for stopping by
